I got a 10" sub with a total of four post on the back of it...two pos. and two neg. i took it in to get it a new box and the people moved the posts around..and i cant remember where they go...i noticed a wierd sound from it after i got it back. when i looked at the back i noticed the post were moved...i havent used it since...can you help me put them in the right place?

Some one help me i got audiobahn immortals a they have 4 (-) and 4 (+) how do i hook them up as 2 ohms?

Thats not the correct way to bring a dual 4ohm speaker down to 2ohm bridged.. the correct way is to hook both negatives together, n then both positives together. run 1 wire from negatives to negative terminal on amp. run 1 wire from positives to positive terminal on amp. done

The Diagram shows the impedance in series, in which case the impedance as seen by the amp is 8 ohms (for dual 4 ohm) or 4 ohms (for dual 2 ohm).

If it isnt this way try this, Take the + Lead from the amp to the + on the Sub, Cross from the - on the first side to the + on the other set of posts, then take the - from the second set of posts to the - one your amp. I assuem this is a Dual 4 Ohm and will bring that down to a 2ohm which induces more power from your amp and should be louder it could be 2X2 1

Almost all car batteries have 2 pos and 2 neg. More precisely, 1 pos post and 1 side connector, 1 neg post and 1 neg side connector. You only usually use use one set or the other depending on what connectors are on the end of your cables. You can connect something else to the side posts if you need to, but generally only pair is used.

OK. Sometimes manufacturers put two flat prongs to each of the positives and negatives of the voice coils. This allows for daisy chaining multiple subs to be easier. Here is how you want to wire your subs in the box.

From the positive post of the box to the positive posts of both voice coils (just choose one prong on each of them, you do not have to connect all 4 of them). So you will have 2 wires going from one post on the box to 2 posts on the sub. Got it. Not go from the negative post on the box, to both negative posts on the subs. Repeat this with the other sub. Now you can hook each channel of the amp to the box regularly pos of amp to pos of box and neg of amp to neg of box.

This set up is called parallel and will drop the ohms resistance of two 4 ohm voice coils to a 2 ohm load. You will get 2 ohms for each sub, thus connecting one sub to each channel. This will allow you to get the max power out of the amp or 150w RMS per your post. Hope this helps.

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.

try connecting power to one terminal and the negative to the other terminal this will bridge the amp

if u have two pos. and two neg. on the back just run a wire from one pos to the other pos and do the same with the neg just run the wire from the box to one of the pos and neg only on one side u have two wires runing to them

Sep 28, 2009 | Kicker CVR12 Car Subwoofer

u should have two pos, an two neg. on the back of the sub run a wire from one pos to the other same with neg. now just run a pos an neg from the box to one side of the sub u should have one side with two wires runing to the pos. an neg. if u need more help let me know [email protected]

I would try running the subs in parallel. Pos to Pos Dual Voice, Neg to Neg Dual Voice. Then Run + to + stereo - to - stereo on both channels.

So you have + and - running to one channel and + and - running to the other channel.

Also your LPF filter could be set too high.

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 Kenwood KAC would be 2 ohm stable.

I ran my sub's in parallel and the amp did not shut off and hit pretty well for long periods of time.

If you are running two dual voice coils.

Bridge amp, run pos and neg to pos and neg outside of box.

neg and pos to one side of sub

The other side of the sub run to the next sub

the other side of the sub to the inside of the box pos and neg.

pos and neg outside of box to the other outside terminals to create a complete loop.

If this isn't a good description post back and I'll email you a picture of it.
