New Deck does not turn on

[tim]

Put a 10amp fuse with a jumper wire in line directly with your battery and hook the red and yellow from the deck directly to it. If it lights up than you know your wiring in the car is fucked and you can start looking from there. If is doesnt light then you know it is the deck(assuming it is properly grounded).

If it lights get a multi-meter and start checking your wires one at a time til you find the culprit.

Good luck!
