Yesterday I jumped started someone and my subs stopped working. I check my fuses. I have power to the amp. But its red which means "protect" and green means good to go. But when I ground it, it doesn't get power at all :/

What does "when I ground it" mean?

Disconnect your subs. If the amp is still in protect after you turn it on, your amp is probably blown.

Are you saying that at some point you ran your amp without grounding it?

'89 Mercedes-Benz 300E

Pioneer DEH-5900UB

(2)RE Audio SX 10"s

(1)US Amps MD3D

3ft^3 @ 37Hz

Blowing up in a car accident doesnt worry me, as long as I'm putting out some major dB's when I die...

No, it was working but they stopped working for some reason... And it wasnt getting power. So I took it a part and put it together and before i grounded it, it had power. but when i ground it, it doesnt have power

First of all, NEVER connect power before ground, and you should not be working on power leads unless they are disconnected from the battery. I suggest you need to go to a local car audio shop and pay for a proper installation and to get your amp tested.

Nope, take it to a install shop before your short cuts and voodoo make the matter worse than it is.

Top Secret, I can tell you but then my wife will kill me.
