Hey guys... I got a 2003 Civic EX and I just purchased 2 12" MTX's, an Alpine CDA-9807 headunit and a Rockford Punch 200 4 Channel Amp. My friend and I hooked it up on the Civic and got it all working before we placed it back into the slot where the head unit goes. Then, we turn the car up, clean up the inside (behind the HU, where the wires are) with electrical tape, and then shut the hood/trunk and then come back out like 5 minutes later to go tune the amp and the Head unit would not come on. We double and triple checked all wires, connection and fuses. Everything was fine. My friend thinks it could be the headunit, but I just bought the damn thing today. Anyone have any ideas that we might have overlooked? Anything would be appreciated... thanks!

isolate and identify! first thing is first, are the wires working internally? is it the radio fuse? did something cross? next, check the wires themselves, do you get 12 volts on constant? 12 volts on ignition with the key in? (need a test light or DMM) if the radio still doesnt powerup, can you take it directly to teh battery and hook it up? will it power on with just those three? the fuse on teh radio is ok?

THEN....... you have a fried unit

how didi you make the connections on the radio? Hardwired or did you buy an interface harness. Solder and tape, crimps more info needed.

who there, use a comma or period sometimes.. anyway

a lot of weird thing shappen back there, when you put the console back in, wires can get lose, they can short, wires get piched somewhere. check all you fuses.
