I tried messing with the controls on the amp and it had no noticeable effect in the sound. Its at a constant low low volume all the time still and changing the volume and bass amount on the HU have no effect. Im starting to think its a HU issue.
try a different source,preferably wired into the same rca's. You can use an mps player and some headphone to rca cables to put a differenct source on it.
If you connect a diskman or mp3 player, make sure the volume is all the way down when you turn it on. I have seen some fried low level inputs from an error in that regard.
