Ugh... only one sub working!

[almost2asian 10+ year member]

Ok... i can only get one sub to work right at a time. I wired my subs to the terminals in the sub box. Then i wired the positive terminals together with a wire coming off it goin to the positive output on my amp, and i did the same with the negative. When this works, i get a really crappy sound coming out of my subs. When i disconnect one sub, the other sub magically sounds awesome. please help!

What subs and amp? Only one terminal cup? Two separate terminals? How exactly are they wired to the amp?

ok there are two terminals on my box.... each sub has the postive to the postive and the negative to the negative.... then from the box, i have a wire running from each positive, connecting, and a wire running from the negative, connecting... then from the positive connected wires, i have a wire connected by a butt cap to the amp... then the same for the negative... the amp has ++ - - on it... and i have it wired to the first + and the first -

One sub is out of phase. Check your polarity on your connections. That should clear up the problem.

how big of an amp are you running? What type?

im running a BX1500d...

i dont think they're out of phase or anything with polarity. cuz like.. if i just run postive to positive, and negative to negative, straight from the amp to either sub, they work.

i cant take my box out of my trunk... i dont think its ever coming outa ctually... i have a subzone box and it weights probably 100+ lbs... also i had to take out my spare tire to make my trunk more deep just to get it in... it took 4 ppl like 20 minutes to get it in

Just run each terminal to separate +'s and -'s on the amp. No need to connect the two terminals together, then run them to the amp.

Try that and see what happens.

same thing.... i tried it already

I still think you have somehting out of phase..Seen it tons of times..But, if you are sure it isn't that, check each sub with a DMM. One could be defective.

yeah they worked fine in their old box... ima go check rite now

this subzone box and my subs, i dun even know the specs for these subs cuz i got them at a flea market, but wow it sounds amazing.... the highs are tight and u can feel em, the lows are loud and semi tight for a ported box... its not bad for daily use and cheap kenwood subs lol.
