Speaking of tweeters, Morel offers nearly identical MDT29's in both 4 and 8 ohm versions. As rated, the 4 ohm is 92 dB sensitivity and the 8 ohm is 89 dB. For a MTM, the 4 ohm would be more likely. So, just by halving impedance and not doubling driver area and motors, you get +3 dB Wiring Your DVC 4 Ohm Subwoofer - 2 Ohm Parallel vs 8 Ohm Series Wiring - Duration: 6:07. Quality Mobile Video 280,779 views. 6:07 Hi all, I'm building a cabinet to house 2x10 speakers, need to end up with 8 ohms. Are there any advantages tone wise to either 2 x 4ohm speakers wired series, or 2 x 16 ohms wired parallel I have a PDX5 putting out 300W @ 4ohms. I can get a deal on a JL 10W3v3-8 (8ohm) sub. Will putting an 8ohm sub on a 4 ohm amp reduce it's load to 150W.. Parallel Wiring - Speakers of equal impedances you divide the impedance value by the number of speakers. To determine the wattage you add the wattage of the speakers together. If you wire (4) 16 ohm speakers in parallel you'd have a 4 ohm cabinet. (2) 16 ohm speakers in parallel would give you an 8 ohm cabinet

Get 8 4 Ohm With Fast and Free Shipping on eBay. Looking For 8 4 Ohm? We Have Almost Everything on eBay Sometimes an 8 ohm speaker might be 7 ohms, or at times 29 ohms, or even 44 ohms. It's all over the place. All speakers have an impedance rating in ohms, which represents how difficult the speaker.

The impedances add in a series connection. If speaker A equals 8ohms and speaker B equals 8ohms, the total load is A plus B, or 16ohms. If you string three 8 ohm speakers in series the net impedance will be (3X8) 24 ohms.If resistance decreases, then current has no opposition and that causes the amp to overload and burn out. For instance, two 8-ohm cabinets wired in parallel will have a total impedance of 4 ohms. Two 4-ohm cabinets would have an impedance of 2 ohms. Remember, we said if your amp can't handle a 2-ohm load it could go up in flames. That's why this is so important If all of the speakers have a common impedance, you can simply divide the common impedance by the total number of speakers to get the net impedance. Examples: Two 8 ohm speakers wired in parallel will have a net impedance of (8 divided by 2) 4 ohms. If you have three speakers, each at 8ohms, divide 8 by three to get a total impedance of 2.66ohms.

Eight-ohm speakers can be run with a 4-ohm amp. One 8-ohm speaker plays loudly with only half the current from the amp, but if two 8-ohm speakers are connected in parallel, the resistance in each speaker falls to 4 ohms to match the amp Note: If more than 2 Speakers are connected in Parallel, so long as they are all the same impedance then the net impedance of the load is equal to the impedance of the one Speaker divided by the total number of Speakers. For Example: Three 8 Ohm Speakers in Parallel, the Impedance is 8/3 or 2.667 Ohms. A COMBINATION OF SERIES & PARALLEL. In reality this is just two sets of Series Speakers. Is it possible to connect two speakers in parallel and then connect them to one speaker in series? I currently have two vintage speakers (8 ohms each) connected in series for my center channel (of a receiver that puts out 80 watts per channel at 8 ohms). So the vintage speakers combined in series are at 16 ohms and receive 40 watts (20 watts per speaker). This seems to work fine. Is it possible to add a newer 4 ohms speaker to this center channel by connecting the two vintage speakers in parallel (now with a combined resistance of 4 ohms) and then connect these to the new speaker (at 4 ohms) in series. In theory would this combine to make an overall resistance of 8 ohms? With the two vintage speakers receiving a max of 20 watts each and the new speaker receiving 40 watts? I have noticed that none of the diagrams online show this kind of configuration. Is it possible / acceptable? Before you buy a 4-ohm speaker, make sure the amplifier or receiver can handle it. It may not be clear, but if the amplifier or receiver manufacturer publishes power ratings in both 8 and 4 ohms, you're safe. Most separate amplifiers without a built-in preamp or tuner can handle 4-ohm speakers, as can most high-end A/V receivers

Speakers in Parallel Calculator - Geoff the Grey Gee

To simplify parallel wiring, pretend your speaker system has a total of 2 speakers with 16 ohms each. What you do next is figure out how many speakers there are (2) and divide the 16 by 2.If you have to provide a lot of power and have a lot of speakers to power then we recommend a 3-phase system because it acts as an insurance system.Think of “loading” as a storage for electrical power. In a nutshell, that’s all it is.

4 OHMS + 8 OHMS= ??? TalkBass

To find out the total impedance value of your circuit all you have to do is add up all the impedance values. Given, Resistor,R1 = 4ohm Resistor,R2 = 8ohm Resistor,R3 = 8ohm Potential Difference,d = 8volts. Refer to the attachment for diagram i)Since we know that R2 and R3 are in a Parallel combination,hence thier net resistance will be given by=> Tube Amps: On the other hand, most tube amplifiers need a load to avoid transformer or tube socket damage. If a mismatch can not be avoided on a tube amp, it is better to go towards a lower impedance rather than too high of a speaker impedance. This may stress the tubes some, but, tubes are cheaper than transformers. Two 8 ohm speakers wired in parallel will have a net impedance of (8 divided by 2) 4 ohms. If you have three speakers, each at 8ohms, divide 8 by three to get a total impedance of 2.66ohms. If the speakers do not have a common impedance, you can use formula 1 for two speakers or formula 2 for more than two speakers

Series, Parallel, and Series-Parallel Speaker Wiring . When wiring speakers with multiple voice coils, it is important to understand the process for series and parallel wiring. Depending on what method you use it will present a different load to the amplifier. This process is the same for resistors as well as voice coils in electrical circuits how can you wire a four 10″ speaker cabinet with 8-ohm speakers into a 4-ohm cabinet, or can you without changing to 4-ohm speaker

The formula for Parallel Wiring is:

Uhhh, higher ohm is higher impedance therefore resistance. Parallel is running 2 loads parallel to one another so getting less impedance total but also less power to each speaker, sort of. Suffice to say, parallel total impedance with 2 speakers = 1/2 the impedance of 1 of the speakers Some resistors display their value by their color. An example of this is a black resistor showing the number 10.

It is important to match the speaker load with your amplifier’s output impedance for a couple of reasons. One reason is that you will get maximum transfer of power. The other reason is that you can sometimes approach dangerous conditions for your amp if you have the incorrect load. When in doubt, it is safer to go higher in impedance to help protect the amplifier. The manner in which your speakers (in a multi-speaker system) are wired together determines the overall impedance.We honestly wanted to say “the easiest way to convert an 8-ohm speaker to a 4-ohm speaker is to throw your 8-ohm speaker out and buy a 4-ohm speaker.” Dual-8 Ohm Subwoofers: 0.8 Ohm; Dual-6 Ohm Subwoofers: 0.6 Ohm; Dual-4 Ohm Subwoofers: 0.4 Ohm; Dual-2 Ohm Subwoofers: 0.2 Ohm; Dual-1.5 Ohm Subwoofer: 0.15 Ohm; Six DVC drivers with Voice Coils in Series / Parallel. Six Dual Voice Coil Speakers in Series / Parallel

The difference between an 8 ohm and a 4 ohm speaker doesn't really become apparent unless you are blasting the amp near its limit. Then it might warm up more and possibly trip protection circuitry if its a 4 ohm load on an 8 ohm amp. Essentially you are losing power because of the mismatch. As said before, don't blast it and you'll be fine You don’t. This wiring diagram is for getting wide area coverage on one zone of output. Are you thinking about a 5 channel surround sound setup? That would require a surround sound receiver and 5 speakers, each wired to its own output.

How To Convert An 8 Ohm Speaker To 4 Ohms - Noisylab

I'm stuck between running these parallel: all 8 ohm speakers at 2.66ohms. all 4 ohm speakers at 1.33ohms. 8ohm 8 & 4ohm 6.5 1.60ohms. I'm running active, so tweeter wouldn't matter. So if someone can tell me the benefits and downfalls of running the above options, that'll be great. Edited August 9, 2012 by _Vinc Hi Eric, thanks for your comment! Hopefully one of our knowledgeable readers will be able to chime in with some insight on this.

I'm not sure whether the speakers have parallel or series connections on the back. Still looking for that info. We intend to run 1 8ohm and 1 4ohm speaker on each channel - at this point. My guess is series = 12 ohm... out of the question, and parallel = approx 3ohm - which is ok

And the balance comes with impedance. To state another way, resistance from the speaker needs to match an amplifier to make sure the amplifier is at its best.But changing ohms doesn’t only affect current or power. We also have to look at amplifiers and how they relate to ohms.

Can you use 4 ohm speakers on a 8 ohm stereo system? - Quor

  1. Ordered a replacement, same part number, SAMMI cw77b1o a 10w 8 ohm speaker. When the speaker arrived it is marked cw77b10 10w 4 ohm. Installed the new speaker, it works, but then started to worry about drawing to much current through the amplifier circuit.

My 100W 8 Ohm speakers sound beautiful paired with the Kenwood receiver so loosing sound quality when I upgrade is a HUGE con. I downloaded the Sony STR-DN1040 manual and it said that the receiver can also run at 100W x 7 @ 6 ohms 20- 20kHz 0.9% THD 2ch. I know running this would be better given the frequency range Two 8 ohm speakers in parallel is 4 ohms, and the power will be split between them. However, unless the amplifier is rated for 4 ohm operation, you will not get the same total power out of the. I'd like to use a 4 ohm tube amp with my 8 ohm enclosed recording speaker. Would putting a 100-watt 8 ohm resistor in parallel work well or would the fact that it's resistor and not a speaker mess with the sound? I don't mind if the volume is lower. Since it's for recording I'm just looking for tone

Almost certainly yes, unless the 4 ohm rating indicates a very low impedance <1 ohm at some frequency. The 4 ohm and 8 ohms are nominal values. If you measure a 8 ohm speaker you will find the impedance will vary over a range of approximately 3. I am mounting 4 speakers on a patio that’s 16’ W x 60’ L. How should I mount these? What I mean is should I mount speaker A as left, speaker B as right speaker C as left and speaker D as right? Or speakers A/B as left and C/D as right? Then do I wire them in parallel or series?

The circuitry of the amp must be able to handle this increase in current at the reduced resistance.

Two 8 ohms speakers in parallel - Answer

When n is the number of Elements

All of this balancing and figuring out how to make your speaker sound good starts with knowing how much ohms your speaker is packing. This current will be drawn on a 2:1 ratio with the 4-ohm speaker being the 2. This means that 0.577 amps will be drawn by the 4-ohm speaker and 0.289 amps will be drawn by the 8-ohm speaker. When only the 8-ohm speaker is in place, then 2/8 = I^2, I = 0.354 amps

Two resistors of resistances R 1 = 100+/- 3 ohm and R2= 200 +/- 4 ohm are connected (a) in series, (b) in parallel. Find the equivalent resistance of the - 136222 NOTE: I get a lot of people asking how to wire 2 speakers up together and maintain the same impedance as one of the speakers, for example taking 2 8 ohm speakers with the end result as an 8 ohm load.It is impossible - your only options are to wire 2 8 ohm speakers in parallel and get a 4 ohm load, or 2 8 ohm speakers in series and get a 16 ohm load (please note that things of this nature are. Front speakers are wired in parallel. (door + dash) 4 ohm speakers would mean 2 ohms to the front channels at the deck. Parallel wiring decreases ohm load while series increases. The OEM front speakers were 8 ohm so the stereo saw a 4 ohm load. Having said that, I've had 4 ohm speakers in my SQ for years with no ill affects

A resistance of 3.6 ohms indicates they wired two 8 ohm drivers in parallel (with an inductor in series adding a little resistance). Resistance is not the same as impedance. Seriously, read the. Basically if you only want to run a single cab and get the most power from the your amp, it should be a 4 ohm. But if you plan on running two cabs, each one should be 8 ohm, because two 8 ohm cabs are (when hooked up in parallel) a total of 4 ohms (for some reason)

So if you have 2 4-Ohm SVC type subs wired in parallel, you will end up with a 2-Ohm load (perfect for most subwoofer Class D amps). If you have 2 8-Ohm SVC subwoofers wired in parallel, you net a 4-Ohm load (perfect for most 2-channel amps bridged). Here is a small diagram of wiring in parallel from the JL Audio website ( www.jlaudio.com Figuring out the total ohms for parallel wiring is taking the ohms of 1 speaker and dividing it by the total number of speakers.Two 4 ohm speakers = 2 ohm load Two 8 ohm speakers = 4 ohm load Two 16 ohm speakers = 8 ohm load Wiring Configuration for 2 Speakers in Series An easy way to tell if you have a series circuit is by turning a resistor off. Once you’ve turned off your resistor, does the whole circuit stop working? Three 4 Ohm Single Voice Coil (SVC) Speakers : Option 1 (parallel) = 1.34 ohm load Speakers wired in parallel Recommended Amplifier: Stable at 1 ohm mono : Option 2 (series) = 12 ohm load Speakers wired in series Recommended Amplifier: Stable at 4, 2, or 1 ohm mon

Solid-state Amps: Most solid-state amplifiers would rather look at an open circuit (no speaker at all) than a load. Therefore, you can usually use a load that is higher than the recommended load. Do not use a lower impedance load, as this could cause serious damage to your SS amp. A 4 ohm resistor and an 8 ohm resistor are connected in series. If the current thru the 4 ohm resistor is 2 amperes, the current through the 8 ohm resistor is 1) 1 A 2) 2 A 3) 0.5 A 4) 4 A SHOW ALL WORK PLEASE

Once you’ve inserted it, make sure the wire is spread over the plug. After that, place the cover of the banana plug over and insert it into the terminal of the amp. Two 8 Ohm Speakers... Series Or Parallel? Discussion in 'Amps' started by Poodlesrule, Nov 28 Need to see if you amp is rated for a 4 ohm load. If only rated for 8 ohm and above, wire in series to get 16 ohms. SamIV So two 8 ohms in parallel for a total load of 4 ohms would be best. (semiconductors are relatively low impedance).

How to hook up speakers correctly for proper impedanc

Problem: A 2 ohm resistor and a 4 ohm resistor are connected in parallel to a 6 volt battery. The power dissipated by the 2 ohm resistor is: 1. 8 W 2. none of these 3. 9 W 4. 6 W 5. 18 W Based on our data, we think this question is relevant for Professor Giovambattista's class at BROOKLYN CUNY Parallel Speaker Wiring combines all Speakers (+) positive Speaker leads together, and all (-) negative Speaker leads together. Parallel Circuits are the simplest to wire because adding a Speaker is as easy as connecting the new Speakers (+) positive lead to the (+) Speaker wires of the other Speakers and the (-) negative lead to the (-) connection of the other Speakers. It's not really going to affect your 8-ohm speakers other than possibly lowering the maximum output volume (and thereby protecting your amp from overcurrent into the 4 ohm ones). It's generally safe to use higher impedance speakers than rated, but lower is riskier since it can result in unsafe currents in the amplifier I would like to put 3 speakers on The left side of my room and 3 on the other. I’m trying to decide if I need to run them in series or parallel? The space is a 40×40 area.


The tweeters are both likely 8 ohm, but if its make for 4 ohm tweeters and you put 8 ohm tweeters on there, the result is the same, x/o frequency doubles. If they're both 8 ohm, you'll have a 5.2khz woofer cross point combined with a 2.6khz cross at the tweeter, which isn't ideal but as said this is temporary anyway Nigel Brent studied at the EMI College of Electronics in London England and subsequently formed a Design Company in Los Angeles, California. His current projects include a range of Miniature Amplifiers for both Traditional Stereo and 70 Volt Applications. Being small enough to fit in your hand, they can be easily concealed, reducing the chance of theft.

Not only is alternating current switching directions, but it also changes the direction of voltage. Again, understanding both current and voltage helps us understand resistance better which in turn helps us convert an 8-ohm speaker to 4 ohms.To give you an example of how confusing this is, imagine 2 8 ohm speakers. A parallel wiring turns those 2 8 ohm speakers into a system of 4 ohms total. 3 ohm speakers vs 4 ohm load from amp. Discussion in 'Audio & Video' started by blacksandtaco, Mar 2, 2009. Post Reply. Mar 2, 2009 at 5:48 PM #1 #1. and in addition to that even 4 ohm speakers never reach 4 ohms unless they are played at their resonant frequency, 99% of the time speakers are presenting anywhere from 4-15 ohms to the amp.

If you connect two 8 ohm speakers in parallel, then the effective impedance is 4 ohms. Connect this to the amp and it will be able to deliver its maximum power (150 watts). However this 150 watts max will be shared equally by the two speakers, so they will each receive 75 watts max If you have two speakers in parallel, the higher impedance speaker takes less power. For example, for an 8 ohm and 4 ohm speaker in parallel, the power shared is inversely proportional to the resistance, so the 8 ohm speaker absorbs half the power of the 4 ohm speaker the only scenario where this would be true is running a 4 ohm cab off of the 8 ohm tap of a tube amp. with a solid-state amp, the 4 ohm load would draw approximately 30% more current, and all other things equal, will be significantly louder than an 8 ohm load. 3dB is a lot; all things considered. his valvestate amp is definitely solid-state stereo: 2 ohm, 4ohm, 8ohm mono parallel: 1 ohm, 2ohm, 4ohm mono bridge: 4ohm, 8ohm, 16ohm : Output frequency band : 20Hz - 20kHz : THD (20Hz - 20kHz) stereo: 0.005% or less (250mW-600W, both channel operation) mono: 0.005% or less (250mW-1200W) Cross modulation distortio TECH TIP-- If you can 'stand' wasting a little power, here's how to use 8-ohm and 16-ohm speakers together: a) place an 8-ohm/high-wattage power dropping resistor in series with the 8-ohm speaker...thus making it look like a 16-ohm load. b) connect the 16-ohm speaker in parallel with the series-connected 8-ohm speaker-plus-8-ohm dropping resistor...thus making a total combination load of 8.

  2. Thanks for your comment. I’m hopeful that another reader will be able to chime in and give you an answer on this one!
  3. With two 8 Ohm speakers in a cab it would work as follows: Left input would be 4 Ohm using both speakers (Parallel wiring) or 8 Ohm when used in stereo (If two amps are being plugged into both the left and right input) When using two 8 Ohm speakers, the only mono options are 4 Ohm (top left jack) and 16 Ohm (bottom left jack) The only case in.
  4. These voice coils can also be wired in parallel to present a single 1 ohm load. Now lets say you have a brand z amp that puts out 250w at 4 ohm, 500w at 2 ohm, and 1000w at 1 ohm. Now, with this amp you would probably wire the sub in parallel to get the most out of you amp< considering also that the sub can handle that much power

  5. Other resistors have no color to denote their value. Resistors with no value are marked with a +/- 20%.

What Speaker Impedance Means and Why It Matter

  1. Ex: If you wire 4-16 ohm speakers in parallel, you would have a 4 ohm cabinet. 2-16 ohm speakers in parallel would give you an 8 ohm cabinet. If you were using 4-100 watt speakers, you have 400 watts power handling
  2. As you can see the measurement differences between the low setting (less than 8 ohms) and the High setting (8 ohms or more). This is the reason I usually recommend keeping this switch in its default High setting and using common sense when mating a receiver with inefficient 4 ohm speakers in large rooms
  3. Series Circuits are “voltage dividers”, and using Ohms Law, one sees the result as a decrease in amplified voltage audio signal to each Speaker. Since Series Circuits are “voltage dividers” each Speaker sees a percentage of the amplified output from the Amplifier.
  4. 4 ohm guitar amp -8 ohm speakers I'm not sure if I am asking this on the correct thread or not, but here goes. I have a Behringer GB412s speaker cabinet with 4- 12 inch speakers. The cabinet is rated at 8 ohms. I just ordered a Behringer Virtube VT100FXH amp head online. Ok, so I am a dummy
  5. An 8 ohm woofer will have twice the damping factor of a 4 ohm woofer. When the bass hits, a woofer will generate back EMF that controls the motion of the cone, which is what makes bass sound tight. An amplifier with a high output impedance going into a low impedance speaker load will be much more sloppy than the other way around

16 ohms in parallel with 4 ohms = 3.2 ohms, but a 4 ohm speaker may have an impedance curve that dips down well below 4 ohms. If you have a fairly beefy receiver that is rated for 4 ohms (very few are rated for less than that), AND you are careful not to push it to the point where the output stage overheats or audibly distorts, you should be. Another part of connecting the wire is twisting the wire to create a single strand. This makes it easier to fit into the terminal.When current meets resistance, power is multiplied. This is the case because current times resistance equals power.The point of telling you this is by knowing which circuit you’re working, you can determine how much, and how to get your desired impedance.

The impedance of a subwoofer coil is expressed in ohms. Impedance is the amount of electrical resistance, or load, a sub puts up against an amplifier's output. Subwoofer voice coils usually come in 2-ohm, 4-ohm, or 8-ohm impedances. The value is often found printed on the magnet, if you're unsure of what you have. Series wiring and parallel wirin Remember, resistance, current, and voltage working together is all about balance. Lowering speaker impedance by switching from 8 ohms to 4 ohms lowers resistance. Wiring two speakers in series doubles the impedance of one speaker. Wiring two speakers in parallel halves the impedance of one speaker. For example, the diagram below shows you how you can turn a pair of 8Ω speakers into either a 16Ω or a 4Ω load. To make a two-speaker 8Ω cabinet, put two 4Ω speakers in series 8 ohms? you have two 8 ohm resistors in parallel, which is 4 ohms, in series with 12 ohms, total of 16 ohms With 12 volt battery, current is 12/16 = 0.75 amps.This splits between the two 8Ω resistors, so each get 0.375 amps power is I²R = 0.375² x 8 = 1.125 watts

  2. Wiring Configuration for 2 Speakers in Parallel : Two 4 ohm speakers = 2 ohm load Two 8 ohm speakers = 4 ohm load Two 16 ohm speakers = 8 ohm loa
  3. The Amplifier sends an audio signal (+) out through the (+) Speaker output into the first Speaker; then the signal is sent from the first Speaker’s (+) and so on until the circuit is complete with the (-) of the last speaker is connected the Amplifier’s (-) connection.
  4. But if you are connecting Two 8 ohms plus 4 ohms sub then the best way to connect them is series the two 8 ohms together and parallel 4 ohms sub and this will equates to 3.2 which is closer 4 ohms rather than 2.6 ohms if all is parallel. Good thing about it too is you don't need to change anything on the amp
  5. The best way to find out if your stereo system can handle lowering impedance is to use a multimeter and measure the ohms before even doing anything.
  6.  Consider the S/P 1 connections. Again we'll assume that each speaker's impedance is 8ohms. Speaker A is connected in parallel to speaker B and together they make up a network equal to 4ohms. Speakers C and D are also connected together in parallel and also make a network equal to 4 ohms. Now, the two networks are connected in series to give us an 8ohm output.
  7. How would I wire a 3 channel LCR speaker to be a center channel, Each channel is 8 Ohm. The receiver, an Onkyo, will do 6 OHM.

If you’re using a digital multimeter then what you need to do first is set the resistance to the highest range possible. Then make the 2 probes touch each other. You’ll know it’s right if your meter displays 0 ohms of resistance.For those who went the extra mile and got banana plugs, insert the wire into them. Banana plugs also have markings which let you know where to put the wire.It is often assumed the Amplifier is producing less output, but it still produces the same output, because each Speaker only gets a percentage of the overall power. The biggest difference is in their prices, but this also depends on the brand and size of subwoofers you choose. A 2ohm subwoofer would be pricier than a 4ohm subwoofer, a 2 ohm subwoofer would range between $50 and $200 depending on the brand you choose to purchase. There is also a difference of about 2.5dB between a 2 ohm and a 4 ohm.

Once you know how much your impedance is worth, then you’ll know whether you need to adjust or stay where you are. 4 Ohm rotary L-pads appear to be nonexistent, which is surprising considering the number of nominal 4 Ohm drivers out there. But if I take a stereo 8 Ohm L-pad and parallel the resistive elements and wipers (jump terminals 1 to 1, 2 to 2, and 3 to 3), this should give me a workable 4 Ohm unit, right Another formula which affects power is voltage times current. Whether the voltage or current increases doesn’t matter, power increases regardless.

I realize that two 8 ohm speakers in parallel + 4 ohm and would be better and some say wire an 8 ohm 100 watt resistor in parallel with the speaker to make a 4 ohm speaker so what do you with the requisite information say ? by the wa the speaker sounds KILLER with this amp but I have not craked it or played it for long duration The key for the amplifier is to drive a load as the same impedance with an amplifier’s output impedance. When you connect two 8 ohm speakers together in parallel it brings it down to 4 ohms.. You take the positive wires from 2 diff speakers and connect them to 1 of the positive connections on your amp, then you take the 2 negative wires from your speakers and connect them to 1 negative connection on your amp You can't. Two 4 ohm speakers in parallel equal 2 ohms, and two in series equal 8 ohms. It is possible to wire four 4 ohm speakers so that the load is 4 ohms though. Put two in series (8 ohms. Yes, if the amp is rated at 1000W under a 4ohm load, and you're running two 8ohm cabs in parallel, the amp will see a 4ohm load, and each cab will see 500W of power. In this configuration, you'll want to make sure that each speaker cab is rated for at least 500W RMS power.Don't confuse this with Peak power handling. The peak power rating indicates how much instantaneous power the speaker can.

An amp that is 4 Ohm capable will have no issue driving an 8 Ohm load, so the amp side is not so much a factor unless it is insufficient for the load. So back to the speaker itself, a 4 Ohm of the same sensitivity will draw more current from an amp than an 8 Ohm one. It will not sound better or worse IMO, just require the more power to achieve. Therefore the resistance of each Speaker is added together, For advanced installations with Multiple Speakers, Series Speaker wiring can be used to increase the resistance of the “equivalent” or “overall” resistance that the Amplifier sees. This allows the Amplifier to run cooler and more efficiently.

Note: If more than 2 Speakers are connected in Parallel, so long as they are all the same impedance then the net impedance of the load is equal to the impedance of the one Speaker divided by the total number of Speakers. Example: A 4-ohm speaker and an 8-ohm speaker connected in series, it's power shared or utilized is proportional to the resistance; this means that the 8-ohm speaker would take in twice the power of its 4-ohm speaker partner. However, if there are two speakers connected in parallel, the speaker with the higher impedance will take up less power

Whenever you see multiple 4 ohm jacks on any Boogie, they are always wired in Parallel (more on parallel wiring in a later post). The two 4 ohm jacks TOGETHER are primarily intended to facilitate two 8 ohm cabinets while either one of the 4 ohm jacks is designed to accommodate just one 4 ohm cabinet. For the complete speaker connection guide. If you take the amp's 8 ohm rating, you can derate it to see what safe 4 ohm load it can drive. An amp that can drive an 8 ohm speaker at 150W can drive a 4 ohm speaker at 75W. The maximum current the amplifier is designed for can be figured from its output power (P1) and designed load impedance (Z1) So using the 4 ohm tap there will be a slight mismatch, but one that any well built amp should be able to tolerate. To be sure it's ok check with the manufacturer. I've run a 16 ohm 4x12 and 8 ohm 4x12 together for years in my custom amp with zero problems. All things being equal the 8 ohm cab will be slightly louder than the 16 190 watts RMS x 2 in bridged mode (4-ohm stable in bridged mode). I would recommend using only one 4 ohm voice coil. That subwoofer isn't really a good match for your amp in this case, since the amp isn't 2 ohm capable. When wired as an 8 ohm setup (series) it can't develop the same power as a 4 ohm, so that's not a good choice It is totally ok to run a 4ohm amp into a 16 ohm cab. The rule is that you can mismatch ohms as long as you mismatch lower rather than higher. Example....I have a Traynor Bassmaster which is a 8 ohm amp. I run this amp into my Marshall speaker cabs which are 16 ohm cabs. I have mismatched the ohms, but the amp puts out less ohms than the speakers Two 8 Ohm speakers wired (hooked up) in Parallel results in a 4 Ohm load. It's easy to calculate the effect of a resistive load when all the speakers are all the same resistance. It is really not suggested to wire different resistive load values in Parallel (8 and 4, 16 and 8 etc.
