just got a new car and it came with a stock si radio with a lighting amp hooked up to mb quart speakers (4) and a 10in jl sub. It worked fine for a couple of days and now, everything works, but no sound. The red protect light is on. Checked barrel type fuse right by the battery and the two fuses in the amp and they are fine. Took all the wires out except for the power, remote and gound and nothing still, just the damn red protect light. ANY HELP?????
