Check to make sure that there are no stray wires crossing into other inputs in the amp, if everything checks out OK then the problem is internal.

run them straight and dont use the cross over. One speak on right channel and the other on other channel. Then turn up amp settings 7/8 the way up and control the rest from your dvd/cd player.
