hey guys..i just installed 2 10" warren g subs to a fosgate 1200 watt amp off of the stock face (i used that little speaker wire to rca box). Now only my left sub is firing. I know the box is wired good because if i switch the wires the right sub runs (but its running on the left channel) now ive checked the wireing for the speaker wire to rca box but still i am getting nothing.
So basicly ive checked

RCA wires
Speaker Wire -> rca converter
Bolth subs
amp
....

what else could cause this?

 

Swith the rcas going into the amp

 

one might not be working... when i use to work at best buy one of my co workers and i were installing my subs ... we did it pretty quick but we didnt understand why the other one isnt working... we wired em to a two channel amp but didnt work.. only one did so then we bridged it and it still didnt work so we decided to stop (after like 3 hrs) and just to back to best buy and get a new one so we did and it worked fine

 

a new amp? because i know bolth subs work.

 

List your Equipment!!!!!!!!!!!!!

 

the signal changer (RCA box) should have adjustments on it. I know if I turn both signals (Left and right) all the way up, one doesn't work. Try lowering them both all the way and turning them up slowley.

 

new amp and subs...alpine...hint hint
