Sounds like you may have shorted a power mosfet or more than one. I'm pretty sure that is what is going on. I've done it myself. I repair car amps and install car audio systems for a living. You need to test the transistors with a digital volt meter set to diode check. Let me know if you know how to do this, if not I can help you. If you need it repaired and don't know how to do it I'll be happy to repair it for you if interested. I am the cheapest you will find anywhere. People send me their amps from all over the U.S and Canada. Good luck and hope to hear from ya!

the problem is mostly with your audio side of the amp. i have a 800 Rockford punch series amp hooked in series running at about 15 vdc at 2 ohms stable for now. but the amps left front power side transistors overloaded and smoked out, i will be replaceing my mosfets soon. Now on that side your issues apear to be related to the signal side of the amp. when you hooked the amp up tell me breifly did you hook the rca inputs to the back of the sterio and did you select the proper rca inputs for the amp? also note that amps have a potentiomater that can be tuned up or down to allow the volume or wattage to go up or down threw the system. if it's turned all the way down you'll here nothing. but often you'll get a pop sound or quickly see the speaker move a bit. this indicated the signal side of the amp has signal comming in but no output, just look for a turnable small screw inside the amp top or side. and turn up acordingly. note: to much output will damadge your system. not just the amp. ;)

Check you inputs to verify you have a signal coming in, if signal then check outputs try a speaker that you know is working and plug it in if that speaker plays then the subs/ or speaker wiring is bad, if it doens't play then you probably have a blown output transistor on the amp or possibly a terminal ground/positive has come loose on the inside..
