Hey guys, yesterday while driving my speakers and sub cut out and didn't cut back in. I have a small system, two speakers and two subs. All connected to a Alpine MRP-550 4 Channel Amp. It's been working well for about 4 months now (minus winter when car was parked).

Well, anyways after my speakers and sub cut out. I decided to take a look at the amp and saw that the amp power light was dimming on and off. So I easily could tell that it wasn't getting enough power. So I checked my ground and fixed it and now my amp power light is solid and bright, so its getting enough power. However, I'm not getting sound out of my speakers or subs again.

I've checked the fuses, I tried plugging in my iPod into the amp with an RCA. Neither helped me figure out my problem. Any idea guys? I'm really hoping my amp's not toast.

One bad speaker is going to be enough to send the entire amp into protection. Disconnect all the speakers and reconnect one at a time. If no ouput with one speaker, amp is going to be toast.

Well, I finally got around to checking my amp. I found a problem. The amp will be receiving 12.5 V when off, but as soon as I turn the car (and deck) on, it'll quickly drop to ~5 V. Any idea what the problem is?

Sounds like an amp circuitry problem, amp might be toast....

That's what I'm afraid of. Any one think theres a way I can find a solution to this problem?

Not without taking the amp apart and testing everything. Try another amp. Even if you can only find a 2ch just to test but it sounds like an amp issue to me. The bad ground may have started the issue ....

I'm thinking of taking it to S&S electronics. Anyone know roughly how much it might end up costing me? I've heard good things about them.
