Just like he said, the amp powers on but puts out no signal to the subs. Yes I tried all the troubleshooting I could. 9volt battery to subs they pop, changed head units nothing, new rca's nothing, put my ipod with rca cables to the amp and still produced no sound. I also put another amp in the car and it worked so no power or ground issues.

Take the lid off and see if there is some broken solder joints or anything visibly wrong.

If there is just touch them with a soldering iron to fix them.

If not... I don't know what to tell you...

yes I did take the cover off and there is nothing visibly wrong. No disconnected wires, no burn marks.

If the RCAs are loose, look close to the solder joints on the circuit board where the RCAs are soldered in...

The problem might be there......

although there is some "burned" looking connection at the opposite end of the rca's. There is a gold heatsink covering the chip I presume underneat. I'll try and get some pics asap but probably won't be able to till tomorrow.

the rca connections on the board are clean.
