i have a rockford fosgate t1 12" subwoofer in my car. it has 600 rms and i have 2 kenwood 2 channel 800 watt amps. i hooked up each voice coil to the left channels. my amp has power but my sub wont turn on. i connected the wires from the sub to my amp correctly cuz they work in my friends car but not mine. i think it may be my remote wire or someting. i know its not my RCA's.
Chris if the sub is DVC and you wired all 4 wires 2 positives and 2 negatives to the left channel of the amp then thats your problem. If you are not wiring to 2 coils together then you need to hook one coil to each channel. You can't hook up it up with both coils on 1 channel and expect it to work rewire it different. Also if it was your remote then the amp wouldn't come on. Also make sure your gains are turned up on the amp. Good Luck
