[QUOTE="keep_hope_alive, post: 8653884, member: 576029"] If the amp is on, but not making any sound, you may have a failure based on the tests you've described. Work all of the switches and knobs in case resistance built-up over time. Using a DMM to verify voltage on the power and remote is step one. Step 2 is to play a 60Hz test tone and measure the output terminals (no wires connected) with a DMM to look for voltage (VAC). This lets you safely play with gain and settings without concern for damaging speakers/subs. If you measure voltage (more than 10VAC) than the issue is probably in the sub box wiring. I've seen sub box terminals fail and lose connection. [/QUOTE]
