2 Subs, 1 Box

beretta01 · May 12, 2007

Hi...I gotta friend thats got 2 Kicker 12" subs in a box he built by himself. The box is sealed and both subs are in the same space....I've always heard that you had to wire one sub normally and then reverse the other(positives to the negative terminal) one because its sealed and when they both hit the same notes it will create some suction in the box...I'm just making sure that Im right...thanks!!

Nope.

Wire them positive to positive and negative to negative...Unless you're going to bridge it (most amps will allow that)...In which case, it'll be slightly different, but not how you're describing.

Thanks for you reply...he was showin me his box and he pushed #1 sub in and the other one(#2) popped out as much as he pushed the other one in....both subs are in the same space so i always thought you had to wire them so when one was pushing out, the other was coming in. When would you wire it that way?

Having one push and the other pull would cause sound cancellation. You will always want your subs phased the same, and usually on the same plane.

Also, make sure you have them wired correctly, there are several ways that subs can be wired. And how they are wired can mean life or death for your amps.

Hmm.....Im not sure where I heard the opposite wiring thing. I thought it would only cancel out if it was in a ported box, not sealed...alright, thanks alot for your help!

you could put them in series to have the same power going to each sub. wire the pos off the amp to the pos on one of the subs. wire the neg off the amp to the neg on the other sub, than connect the neg off the first sub to the pos on the second sub.

Doesn't matter how you wire them, they will still split the power equally between them.

not sure of the terminology, but the only time you would reverse the phase is when running "isobaric". That is when the speakers are facing each other and mounted together.
