Is the amp a single channel? If so, the only way to connect the subs (without overloading the 2 ohm stable amp) is to wire each sub's voice coils in parallel (2 ohm) and then connecting the subs in series (4 ohms). If the amp is two channel, the subs can have their voice coils connected in parallel (as before) and then each sub connected to its own channel.

In short yes. And is very common even has its own term called bridged. Taking two channels and making them one. I would hope that you are running a cap. that's going to put out a lot of power and stress on your battery

ok im going to try to explain this you have 2 voice coils , i will refer to as vc1 and vc2, you take vc1 positive and connect to vc2 neg then use vc1 neg and vc2 pos to the amp according to pos and neg signs.

I have 2 10" Kicker Comp Subs


That amplifier is only rated at 150 watts at 4 ohms, or 300 watts at 2 ohms. Not a very strong amp to run 2 kicker comps. My guess is you have the subs wired wrong for your application. There are 2 types of subs, one is a dual 4 ohm, and one is a dual 2 ohm. Most people bridge these coils together and that cuts your ohms in half. For example. Lets say you have the 10cvr104 subs. Thats the dual 4 ohm sub. You wire the coils together in parallel, now its a 2 ohm sub. You have 2 of these subs running off of your amp, if they are hooked up in parallel, now you have a 1 ohm load, out of the amplifiers normal operation. Your amplifiers internals heat up really quick and there is a thermal overload, putting your amplifier into circuit protection mode. My suggestion for wiring your subs is as follows: for each speaker, wire the coils together like this- positive coil1 to negative coil 2 and negative coil 1 to positive coil 2. That is called running in series, and doubles your ohm load. Next, we need to wire the speakers together properly to hook up to your amplifier. For this, since the coils are hooked together, you only need to use one set of terminals from each sub. And take the positive from sub 1 and hook it to positive of amp. Take negative sub 1 and hook it to positive of sub 2. Take negative of sub 2 and hook it to negative of amp.

What kind of amp to buy for an alumapro 10 inch sub 4ohm 250watts rms?


Is your sub single or dual voice coil. This will also make a difference in choosing amps. Pretty much any amp that will supply your required power will do. But, if you have a single voice coil sub, you will be wanting to look for RMS power at 4 ohms. If you have a dual 4 ohm voice coil sub, you can wire it to a 2 ohm load. Then you will need to search for amps that supply the RMS requirements of the sub at 2 ohms. The choices are almost endless. I am an RE Audio dealer, so I absolutely know that they will do you well. Hope this helps.

I just needed some help with wiring my p8002 rockford amp to 2 fosgate 10 inch subs i just bought. there 4 ohms a piece and dual voice coil. i dont know much about car stereos but people keep telling me...


Well i tried looking up that amp, but Fosgate sight is down. So assuming that the best power out of your amp is 2ohms off the bridged hookup, and the subs are 4 ohms per coil, the best way is to only use one side of each speaker and hook it straight the the bridge. Only using one hook up wont hurt anything, its just for giving you wiring options. And when adding up ohms of speakers, it goes like this. If you had two 4 ohm subs, that'll give you a 2 ohm load. If you hooked up all your hookups, it would be like having four 4 ohm subs, and would give you a 1 ohm load.

I have 2 15 compvr how do u hook the 2-&da2+ in da back of the speakers.


it depends on the amp your using and the impedence of the coils.(ohms) for general purposes lets say that you amp is designed to run 500 watts bridged mono into a 4 ohm load. Lets also say that your subs have dual 4 ohm coils on them. To achieve the 4 ohm load you would want to run the coils in series on each sub,meaning that one of the positives is going to connect to the negative on the sub the remaining + and - terminals are what you will connect your speaker wire to. you just turned your dual 4 ohm coil sub into a 8 ohm single coil speaker. Do the same thing to the other sub and now you have a pair of 8 ohm subs with a set of wires coming from each. Now parallel those sets of wires together( + and +) and (- and -) and run that to your amp. This will give you a 4 0hm load at the amp

That's dependent on your subwoofers. You will need 2 dual 4 ohm subs wired in Parallel, a single dual 2 ohm subwoofer wired in parallel, a single dual .5 ohm wired in series. Or something similar.

I have 2 positives and 2 negatives on back of my alphasonik sub, do i connect amp to one side or both sides?


Hello gaz69,

Your PSW815 has 2 ohm dual voice coils allowing you to better match the impedance to your amp. Each voice coil is 2 ohms. If you wire them in parallel (both +'s together and both -'s together and then to the amp terminals), the sub presents a 1 ohm load which is too low for most amps. Wiring the voice coils in series (one + to the other - and the remaining + and - to the amp terminals) results in a 4 ohm load.

This link shows the wiring diagram for both options. If you know for sure that your amp is 1 ohm stable, use Wiring Option #1. If the amp is not 1 ohm stable, use Wiring Option #2.

Hope this helps.

make sure that you get dual 2 ohm subs. to get a 1 ohm load, wire each sub in a series. that means the positive from one coil, connected to the negative of the opposite coil. then the other two leads will be your active speaker wires. that will give you a 4 ohm load for each sub. once all 4 are wired like this, you simply take all of the positive wires that you have left, and combine them at the amp. do the same with all of the negative wires. that will give you 1 ohm. just be extra careful to make sure every sub is wired exactly the same, otherwise your sound quality will be greatly reduced.
also, 2500 watts isnt as much power as these subs will take if wired together. it will still sound awesome, but I reccommend turning the level on your amp up just until you hear a bit of distortion, then back it off a hair. being slightly underpowered will cause you to have some distortion in your bass. playing distorted notes builds up alot of heat in the voice coils, and these subs are VERY sensitive to overheating.

Bridging 800a4


That all depends upon whether or not the sub you are running has dual voice coils or just a single voice coil. The 800a4 is a four channel amp; thus the only way you can bridge it will be 3 channel or 2 channel. If you are running a dual voice coil sub then you can wire the amp two channel and get 400 watts x 2 @ 4 ohms. Make sure that you sub can handle this kind of power though.

Here are the specs:
4 x 100 @ 4 ohms (13.8V - <0.05% THD)
4 x 200 @ 2 ohms (13.8V - <0.10% THD)
2 x 400 @ 4 ohms bridged (13.8V - <0.10% THD)
Fuse: External 60A

Dual voice coil wiring to class d amp


The easiest way to think of wiring voice coils and subs is this:
  • Two items of the same impedance in parallel = Half of the impedance
    • 4 ohms in parallel with 4 ohms = 2 ohms
    • 8 ohms in parallel with 8 ohms = 4 ohms
  • Two items of the same impedance in series = Double the impedance
    • 4 ohms in series with 4 ohms = 8 ohms
    • 8 ohms in series with 8 ohms = 16 ohms
In this case, you want to wire two subs, each with dual 4 ohms voice coils, so that the total equals 2 ohms. Your options are:
  • DVCs in parallel, 2 subs in series = 4 ohms
  • DVCs in series, 2 subs in parallel = 4 ohms
  • DVCs in parallel, 1 sub = 2 ohms
With two, dual 4 ohm subs, you can only have 1 ohm or 4 ohm total impedance.
