New Headunit, no power??

thayne

I purchased a double din JVC headunit and a set of component speakers from Crutchfield. I got the speakers wired in (new speaker wires bypassing the factory wiring) and hooked up the headunit and it will not power on.

I plugged the OEM unit back in and it was fine. I have checked and double checked the wiring. I thought it might be the METRA harness so I tapped directly into the factory harness, no luck. I thought it might be the headunit or its harness so I ran to Bestbuy and bought an identical unit to try and still no luck.

I checked the two fuses under the dash that said "audio" and both were good. I checked the 15 amp fuse labeled "audio" under the hood and it was blown. Replaced it with the adjacent fuse (convertible top, which I don't have) still no luck.

Not sure what else to check, getting a little frustrated. I have done numerous audio installs before and never had a problem.

Are there any safety/theft interlocks to prevent it from powering on? It should power on with just power, ground and illumination wires connected, correct?

Any help is appreciated.
