    -Sup, I checked the wires coming out of the HU.. they're not rca wires, though. I have an rca adapter screwed on my box. The connections were fine.

    -I checked the remote turn on wire, also secure at both ends.

    I have Perfect 12.1dvc's. The voice coils are 2 ohms each, and I wired them parallel. I don't think they go outside the range of the amp though.

    I only have this amp running off the head unit, and the power light does not fade. I know nothing about alternators, it's possible that's the problem, the car is 12 years old. But I did a little more testing, and when I turn the gain way up and the it's at a fairly high volume, there is a terrible high pitched resonating in the box (loud!).

    I'm really disappointed, I don't want to send it back. Who knows how long it will take them to fix it, and by then it will be a "double refurbished" amp. Plainly it will be a piece of junk, unless they do a great job repairing it.. which is doubtful since they usually use aftermarket components to refurbish amps. |3astards! Thanks for all your help, if you have any more suggestions I could test before I send it out that'd be great. If not, wish me luck.

    You didn't mention the ground, check that if you haven't.

    Try getting a pair of RCA's from a store, you can return them later, try to switch them, and see if that will make a difference.

    Sounds like a signal problem, RCA's are responsible for delivering the signal, that is where I would start, talk to Chris, he can give some methods of testing.

    The rest of your system stays at the correct level when the subs shut off right?

    Your RCA adapter could be going bad. But I would still think it was the amp unfortanitly.
