for all your needs also good place to make cash!

you could have a bad ground or the power wire could have a short i would start there

check all fuses on the unit, pull them all.
look for a way of resetting the amp.

LEAVE THE MAIN FUSE OUT TILL THE INSTALL IS COMPLETE!!!

that way you wont short a screw driver across the terminals on to the chasis.

Best thing to do is call the dealer and tell them you replaced the battery and the car didn't have an owners manual. They can get pull one off their computer, they just need a S/N from the radio. If that doesn't work, I can tell you a different idea. Don't forget to leave feedback
