Question
i install an alpine head unit to a 93 grand marquis everything was color coded so i had no proble put it together when i turn the ignition on the head unit wont turn on.

Answer
Hello Anthony,
Not a lot to go on but,,,, Have you checked the leads for power with a test probe, meter or lamp at the radio's connector plug? 12v live and 12v ignition. Check for a small 10a fuse in the rear of the radio chassis.
Alpine have always used ISO DIN connectors so no problem there but on some cars the 12v live and 12c acc are swapped.
