Hi Greg,

If the amp is on and the red light is coming on, the most likely scenario is that the amp has died or has gone into protect mode.

Disconnect all speakers from it and then reconnect only one on one channel in non-bridged mode.  If the sound comes back, you can troubleshoot from there (if a subwoofer has blown, it might be providing less than the rated impedance and the amp is trying to protect itself from frying).

If sound doesn't come back, you're probably looking at a dead amp.
