No sound from amp?

My amp is not producing any sound. I have checked all connections, amp is on, power to everything(positive & remote wires), also positve speaker outputs have power, but no sound. Theres not even a buzz. The sound cut out a few times one day & then finally no sound what so ever. I even tried another set of RCA cables :banghead: fuses are all good. Possibly something wrong with the head unit :confused:

A few days before it happened my buddy tested 3 12" subs 0.5 ohm with my amp. could that have messed something up? My amp is 8/4 ohm

so you have an amp that is 4ohm stable minimum and you hooked up a .5ohm impedence on it????

yeah, that could severely screw up your amp, and it probably did

I didnt know the speakers were .5 ohm at the time :disappoin

The owners manual says something about the amp going into a safe mode, but nothing how to reset or anything. Not havin' boom boom sucks man.
