SOURCE: 2 channels not working on 4 channel amp

Well firstly are you using a parametric crossover with your radio and how much rca cables do you have coming you head unit (car radio) if you going to bridge the front up with you rear speakers u wont be able 2 hear the rear speakers try hookinking it up 2 your head unit's front speaker output and have ur rca cable connected to your amp running on your rear output of your head unit by doing this you can use your fader on your head unit to control your front and rear speakers

SOURCE: JBL Sub Amp Wiring Please

it seems rather redundant to bridge a mono amp. Unless the instruction manual states otherwise, i would assume that one speaker output is identical to the other (ran in parallel, like an A or B speaker, not like Left or Right), and you would present the amp with a two ohm load by wiring one speaker to each output. Bridging it may or may not work, but, again, it just seems redundant.

SOURCE: sony xplod 500w 4/3 channel

If the speaker is a 4 ohm DVC (two 4 ohm coils), you can't wire it to get a single 4 ohm load. Try connecting one coil to each of the two rear channels. It may not be as loud but the amp should operate without going into protection.

If the two 4 ohm coils are in parallel, the amp is driving a 2 ohm mono load. That's probably why it's shutting down.

SOURCE: I have Kicker ZX 650 4 channel amplifier and 4 DB

As far as I am aware you need to get 2 ohm speakers. I run a 4 ohm subwear as the Alpine Type R sub is 2 ohms. I'm not 100% on this though but you may get around it by bridging your speakers by connecting both speakers to the amp as normal but swapping the speakers negatives around! That may cause the amp to run as if only at 2 ohms. Hope this helped!

Do you bridge a 850.4 four channel amp when it is 2 ohm stable and ur subs are wired up as series/ parallel and there 2 ohm dual voice coil speakers


If you wire 2 ohm dvc speaker parallel that would give you a 1 ohm load. If your amp is only 2 ohm stable that would not work. You would have to wire the speaker in series giving you a 4 ohm load. Then you can bridge the 4 channels into 2 with each speaker running at 4 ohms.
If you want to run a 2 ohm load use all 4 channels on amp and speakers. No need to bridge.
For 2 ohm DVC:
Parallel = connect both + and - together. = 1 ohm
Series = connect + from 1 channel to - from the other channel. = 4 ohm.

Speaker daisy chaining , am I going to damage my amp etc.?


The Peavey CS4080HZ is intended to place 2,040 watts
per channel into four-Ohm-rated speaker
impedances. The "HZ" suffix is intended
to state the amplifier has a relatively high
impedance output and is optimized for no
lower than four-Ohm loads. Are you strapping in Bridged or Stereo Mode? Bridged Mono Operation
Both amplifier channels can be bridged together to make a very powerful single-channel monaural amplifier. Use
extreme caution when operating in the bridged mode; potentially lethal voltage may be present at the output
terminals. To bridge the amplifier, depress the rear panel Bridge switch to the IN position. Direct the signal to channel
A's input and connect the speakers across the hot outputs (the "+" binding posts) of channels A and B. Only channel
A's input attenuator is active while in Bridge Mono mode. Both connectors are strapped together, so either connector
can be used with a patch cable to drive the input of another amplifier.
Unlike the stereo mode, in which one side of each output is at ground, both sides are hot in bridged mode. Channel A's
side is the same polarity as its input with the minimum nominal load impedance being 4 ohms (equivalent to driving
both channels at 2 ohms) in bridged mode. Driving bridged loads of less than 4 ohms will activate the DDT
circuitry, resulting in a loss of power, and may also cause a thermal (overheating) overload.
Therefore, check the impedance of the cabs for each mode. Remember, if you connect two individual speakers in Parallel (+ to + and - to -) you cut the impedance in half. Two 8 ohm speakers in parallel now have a load of 4 ohms. Series connection + to - to + to -, will double the impedance. Two 8 ohm speakers will have a load of 16 ohms.
I have actually taken a two speaker cab with a 4 ohm impedance and opened up the back to re-do the wiring. I rechecked the impedance with a ohm meter. So yes, be careful. Whatever you do, keep the speaker lengths as short as possible. Buy really good speaker wire or if you make your own, go with 10 gauge wire.

How can i bridge a mtx 9500 using a mono amp?


You cant bridge it to the MONO AMP . You can only bridge subs & speakers to 2 CH & 4 CH AMPS that are bridgeable. Because if it appears that there is 2 channels on a Mono amp its so its convenient for you to hook up 2 4ohm subs to it easily But both channels are actually connect internally together in parallel inside the amp unlike a 2 channel they are separate.

So just connect your mtx 9500 to a plus and a minus and doesnt matter which since all the + terminals of are connected together and - are connected together already.

Whats important is on the side of the sub/box it reads 2 ohms. The lower the ohms the more power the Mono amp will put out. Mono amps are designed to handle 2ohm loads.

If it reads 4ohms The MONO amp is the wrong amp to use cause the power will be weaker. So if you have a 1000 Watt Mono amp at 4ohms the sub will only get 500 WATTS Max while a 2 ohm will get the full 1000 Watts.

If it reads 4 ohms connect it to a 2CHANNEL AMP and BRIDGE IT (connect + of the sub to 1st channels positive of the amp then connect - of the sub to 2nd channels negative of the amp) . The power will be doubled when you bridge it on a 2 channel amp. NOW if it was a 2 ohm sub and you bridged it to the 2 channel amp it will fry the subs and ruin the amp. 2 CHANNELS CANT TAKE A 2OHM LOAD BRIDGED OK.

How can a person bridge a boss cx 150 to operate on one woofer, it works when connected to either output and when connected to one neg and pos from other channel, does the other pos and neg need connected


basically to bridge a amp if you look at the speaker connections on the amp it will say + - / + - those r your 2 channels above below or next to one + of one channel there should be an additional + sign and the same thing with the - of the other channel those are your bridged positive and bridged negative how you hook it up to bridge it is to connect both positives from both speakers to one positive and both negatives from both speakers to one negative this will drop the ohms in your amp as well as your speakers giving you more if your amp is not bridgable then you will not see the extra + - signs you can still attempt to bridge it but is a good posibility that you could blow the amp because it can not handle operating at a lower ohm rating if you are hooking one speaker up you do the same but just hook one speaker up instead of two

It has an A and B channel for spkrs and i have one spkr bridged. do i split the neg to side a and pos to side b or just use one of the channels?


Could you elaborate on how the speaker is bridged?

I think you want to hook up a single speaker to a stereo speaker output.

In this case, you would strap (bridge?) the right and left speaker terminals by running a short wire from A right negative to A left negative. Then strap A right positive to A left positive -- this will give you mono output on either of the right or left speaker terminals -- connect your speaker to either one of these.

Do you know what the ohm rating is for the speaker outs on the amp and also the speaker itself?

Two terminals? bridging theory?


Hello again jm129852,

Having two power and ground terminals allows you to run two smaller wires instead of one big one. It's a convenience. No, you do not have to use them both. They are connected together inside. Yes, you should still use a single fused battery lead. Connect the big wire and fuse holder to the battery and to a distribution block and run the smaller wires from the output side of the distribution block.

When you connect the outputs of a two channel amp to two separate speakers, each speaker gets the power produced by it's channel only. If you are using only one speaker, and the amp is rated to operate bridged, then the speaker will receive the power from both channels, typically twice as much. You do need to be careful when using bridged mode because many amps will only operate safely at a higher impedance when bridged. For example, when operated with both channels connected to separate speakers (not bridged), it may be stable to 2 ohms. But when you connect both channels together (bridged), it is only stable to 4 ohms. Usually, the specifications will tell you the lowest impedance at which the amp should be operated. The specifications for the current RF Punch 500.2 are like this: 125 watts X 2 at 4 ohms; 250 watts X 2 at 2 ohms; 500 watts X 1 bridged at 4 ohms (4 ohm stable in bridged mode). You would NOT want to connect two 4 ohm subs in parallel to this amp in bridged mode. It would result in a final 2 ohm load and the amp would overheat and fail. One 4 ohm sub would be OK, and it would receive the full 500 watts as stated in the specifications. You could connect four 4 ohm subs, two each in parallel to each channel, and the 2 ohm loads on each channel would be OK. Or you could series two of them together for an 8 ohm load, do the same with the other two, and then parallel the two 8 ohm loads for a final impedance of 4 ohms and connect them into the bridged terminals. With DVC subs the connection possibilities get more complex. There are many good impedance calculators online that can help you determine the best wiring solution for various amp/sub combinations. I like the one above at the12v.com web site. Rockford-Fosgate also has one which allow you to select the a number of subs (up to 4), their voice coil configuration (single or dual), and the voice coil impedance. The RF calculator then shows you what configurations are available and what your final load impedance will be.

Hope this helps.

Hi Don,

When you bridge the outputs , do you connect only to the ( + ) speakers terminals for your output. This is what the manual says to do.
