drain power, then power it up again. Is protect on?

you may want to check RCA's and such also

how do you drain the power? no protect doesn't come on... never has. how do i test the rca's? when i move the gain i don't get any power on a dmm

I had the problem with my amp a little while ago and it turned out to be that my ground wire had come loose.

How hard is it to do basic troubleshooting? I dont understand how people can lack this simple skill. Right now the problem could lie anywhere... amp, deck, rca's, wiring, subs etc. Eliminate each of these potential sources one by one by doing tests.. aka, I'd start by seeing if the amp is at fault by wiring it up straight to the battery, hooking up an mp3 player to it for a source, and wire it to some old speakers laying around that you know work. It's really not that hard...

the caps on the board hold a charge-

shunt your + and - battery connections on the amp. just not with voltage hooked up!

if you get a small (or big) arc across them, that usually means the power supply is good to go.

sounds to me like a front end problem. your input stage is not making it to your output stage. is the amp in protect all the time now?

nope, just lights up green and stays green... the amp has never overheated or anything...

Check wiring and mounting for ALL speakers in car. Check speaker mounting screws. I had a set of comps in my front doors, and one of the metal mounting screws for the 6 1/2 was touching against the inner door skin from the speaker basket. All my equipment still worked fine, but couldnt get ANY sound from either of my 2 amps.

Had an alpine amp that powered up but went into protection. Openned it up and nothing was fried/burned/black you know the typical dead give aways. Had my dad test the fet's and a couple were gone. So I just ordered up all new ones and replaced them. Works fine now.
