Ive been having an issue with one channel of my stereo which results in the channel staying at what sounds like preamp level. The right component set just plays extremely quietly as if the amp is doing nothing. I rearranged the crossovers to try to determine where the actual problem lies and found that whatever input and output, the crossover from the channel was causing the problem. After this i got another crossover and when i hooked the problem was still there. Besides rearranging things ive also checked the fuses on the amp and they were fine. Any experience with a problem like this would be great so i know what to focus on. If not I will probably proceed to try a bunch of other rear arranging hopefully locating anything else that is faulty.
