Whats up yall. I have a problem. I just bought a rockford fosgate amp (1001bd) off ebay. The owner said it is in perfect condition. I tryed to hook it up today and no sound. We got power, and when you touch the memory with the remote you get a thump from the speakers, but no sound. I thought I heard some small audio sound for a second at one point but nothing else. What do you think is wrong?
