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?

Re: were the negative and positive post....

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

Re: were the negative and positive post....

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

Re: were the negative and positive post....

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).

Re: were the negative and positive post....

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

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.

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

I think you are asking about wiring you sub in parallel.

Positive on the sub to the other positive on the sub - then off to the + output of the amp

Negative on the sub to the other negative on the sub - then off to the negative of the amp

It will not hurt the sub, however you need to make sure that the amp you are using will be ok with the load you are presenting it.

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.

Basic wiring dictates that with a speaker with 4 voice coils all at 4 ohms each is meant to be wired in parallel. This will put the load at a 1 ohm total load on the amplifier. Wiring in parallel is positive out from amp to pos. to pos. to pos. to pos.. And neg. out from amp to neg., to neg., to neg., to neg..

If they are single voice coil speakers (1 positive and 1 negative terminal on each speaker) then connect from amps' Positive output terminal to spkr. 1 positive terminal, THEN spkr. 1 neg. terminal to spkr. 2 positive terminal, THEN spkr. 2 negative terminal to spkr. 3 positive terminal, THEN spkr. 3 negative terminal to amps' negative output terminal.

That is 3 speakers wired in series. if each spkr is 2ohms, then you will have a total 6 ohm load. If 4 ohm spkrs., then a total 12 ohm load, if 8 ohm spkr., then a total 24 ohm load.

Be careful because amps do not like these odd ohm load totals. You might get away with a 6 ohm total load. Depends on the amp.

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.

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 bertman285@hotmail.com

try reconnecting your rca's from the deck to the amp when finished wire one speaker positive to positive on left channel and negative to negative on right channel then connect the 1st subwoofer. if all power and sound is fine and working turn off power to amp and connect negative terminal of 1st sub to positive on 2nd sub and positive from first sub to negative on second crossing the wires runs the speakers in series another way to try is parralel the speakers wiring by connecting positive left channel output of amp to positive on 1st sub same with the negative then splice positive to positive on second sub and same with negative.

All depends on your amp. Is it 1 ohm stable or not?

Parralell:

positive (pos) on voice coil 1 (vc1) to Pos on vc2 and negative (neg) on vc1 to neg on vc2. Then speaker wire from amp to one vc only = 1ohm load.

Series:

Pos from amp to Pos on vc1. Neg of vc1 to Pos of vc2. Neg of vc2 to amp = 4 ohm load.
