So I have a 1000 watt Pioneer amp. The other day my speaker box rolled onto the amp and cap mounted on it and i lost sound from my subs. power light is on, on the amp and power is good going in and rca cables check out, but i have no power coming from the speaker outputs. im assuming the amp is toast, something on the circuit board? i have done a alittle work on circuit boards so is there something specific i could check and maybe replace? i dont wanna strip the amp down to the board and hook it up and just start checking everything in order, just sounds like a pain. any guesses would be appreciated.
