First off my system consists of 880prs, arc 4 channel, arc 2 channel for sub, diamond comps and coaxs in the back. knu speaker wire and rcas, and jl 4 guage power wires. Now the issue- Sometimes my front right channel dies, cannot seem to find any reason. But it will come back if I turn the volume way up(50+) and it will sound just as it did before for a completely random amount of time, anywhere from 30 seconds to a few days. What could this be?
