I think his clock is seperate in his dash... that's the way mine is. I could be wrong though. It sounds like he blew a bunch of fuses, replaced them, and ended up with the original problem of no speaker output. I was suggesting he test output straight from the back of the headunit, before he even got into factory wiring. If he doesn't have any output on the speaker lines, even after messing with all the menus, etc on the front, he's probably got a bad unit.
