Well if the amp is a mono block for sure you just choose any combination of 1 positive and 1 negative to wire your subs. They are actually summed inside the amp. meaning both positives go to the same terminal inside and both negatives to the same negative on the inside. It's just that way for ease of wiring in high wattage and multi sub systems

I have a alpine type r 15 inch it has two hook ups i cant figure it out i have positive two pos and neg two neg and it keeps cuting out one bridge two amp plz help plz plz


Ok, for starters. Is your sub a dual 4 ohm sub? If so, great. Is your amp 2ohm stable? If so, then great. If you are running one sub, is your amp a monoblock (single channel) amp? Are you running a two channel amp Your subwoofer is a dual voice coil subwoofer. This means that you have to have power to both voicecoils or risk damaging the voice coils. Subs are designed with dual voice coils to give it more control over the cone movement. This results in better reproduction of sound. Anyway, back to wiring.

This is for a monoblock amp (you can also bridge a 2 channel amp) Go from the positive speaker out of your amp to the positive posts of both voice coils. Then go from the negative speaker out of the amp to both negative posts on the sub. And there you have it. It's called a parallel set up. Setting it up this way just dropped the ohms load for that sub to 2 ohms. Less resistance means more power to the sub. Hope this helps

Have a 2000 gmc sierra ext cab pickup and two type R swr-1042d subs and would like to know the best enclosure for the subs to get maximum performance and the best ways to hook up a one channel mono alpine...


it depends on the amp what can it handle. will it do 2 4 or 8 ohm is it 1 ohm stable are the subs dual 2 ohms or dual 4 ohms. 1042s are dual 4 ohm subs so if you wire them both in paralel it will drop both subs into a 2 ohm load for each sub that is pos of one coil to pos of sec coil then pos to pos on amp and same with neg to neg to neg on amp. now if your amp is 1 ohm stable i would do both subs the same way you will get the most power out of the amp. but itll run a littl hot if you dont have adaquate power running to the amp. now i wanna think your alpine amp maybe only 4 ohm stable. i would run both subs like i had said pos to pos then neg to neg now both subs will be a 2 ohm load so what you do to bring it back up to 4 is you run the 2 bridged subs into a series which is pos from one sub to neg of the other sub the remaining pos and neg will run to the amps pos and neg. which will make it into a 4 ohm load. now the last scenereo is your amp is 4 ohm or 2 ohm stable. this is how to wire it to 2 ohms and not 1. take one sub go pos to neg then pos to pos on amp and neg to neg on amp this will make an 8 ohm load with one sub take other sub and do the same neg to pos on sub then pos to pos on amp and neg to neg on amp this will tell amp to run a 2 ohm load. 2 ohms is a good run for these subs if the amp can handle a 2 ohm load. now if you would have given the amp model number i could have looked it up to just give you what you needed but with this short info i gave all possibilities.

How do i bridge 2-4ohm dvc's to a mono block


If you have a DVC 4ohm speaker, and you are using both voice coils, the amp is seeing a 2ohm load.
If you bridge the amp, you CAN run both subs as long as the amp is Two Ohms Stable.
Wire each subs voice coils in parallel.(Positive to positve, neg to neg.) (2ohms) each.
Then wire the two subs in series.(Neg from amp to neg of sub one, pos of sub one to neg of sub two. then pos of sub two to pos of amp.

If it sounds too hard, leave it as you are already running the amp at two ohms.

I bought a 500/1 jl audio amp and also a w7 10 sub


if its cutting off and right back on then check your ground and your power wire makes sure both are connected good and none of your fuse's are blown, either that or you got a wire hooked up backwards in the sub.. but my guess is that the sub is hooked up wrong... that sub should be hooked up in a series or in parallel,

ok if your running just one speaker, it should be hooked up like this and 2 speakers are a different way...

this is parallel :pos to pos , neg to neg, then one wire coming from pos on sub to pos on amp then neg on sub to neg on amp but bridge the amp on your amp should be 2 pos and 2 neg in two different channels take the pos off the sub into the pos on 1 channel and then the neg from sub to the neg on the other channel,

this is series : on the sub it will go pos to neg then the other neg and pos will go to the amp, but make sure the pos and neg r on different sides of the sub, dont hook them both to the same coil

if your need more help give me your email and ill send you a pic of how to do it...

one wire to pos to amp plus to speaker one. now secound speker use neg. to neg. on amp. now take a speaker wire and hook up the remaining neg. post. on the spekers. This will run them in seris like my 4000watt rms amp at a 2 ohm load. Make sur your speakers can handel the rms load of amp. If not they will blow.

The amp says it's 1 ohm stable, so assuming the DVCs are dual 4 ohm, you should be able to connect all "+"'s together and all "-"s together, like the picture below:

As for the amp shutting off for a few seconds, it sounds like it's either:
A) Not getting enough power at high volume.
OR
B) Overheating.

The cap on the +12V to the amp should help, but putting a meter on the +12V might tell you whether it's dropping too low (<11V).

When you first turn the volume up, how long does it work fine before shutting off? Is it with the vehicle running or not?
