First check your power, remote, and ground wires.

Make sure that the ground cable is at least as big as your main power wire.

Make sure that the main power wire is the right gauge in your case I'd use 10ga

MIN. Also make sure that you ran your main power wire directly to the battery. I have seen people (you might not have done this, but it's a warning) try to pull the main power off of things like the decks constant, or the cigarette lighter, the wires for these devices cannot carry the power needed to run an amp over about 50 watts.

You said that you had a factory deck, I presume it doesn't have pre-outs, so you are probably using the wires from the rear speakers to feed signal to yer amp. Make sure that your are usig the high-level inputs and not the low level. If your amp doesn't have High level inputs then you'll have to go to a shop and buy a LOC (Line-Out Converter). This will convert your speaker level inputs into low level inputs.

i have a 4ga wire from my battery straight to my amp. and an 8ga ground wire (it all came in the same kit and it said to use it that way) for sum reason i have ZERO power to my amp, when i first turn on the deck the power light blinks then fades away, neither the protection or power light come on after that. i checked everything (or so i think) and my friend just had the amp in his car so i know its not blown.

any idea whats wrong?
