ok, i have a 2000 stang and it had the premium sound system, not the mach, but the factory one with a cd player, i just installed a new kenwood headunit, a jl amp, and a kicker solo baric sub, as well as new door speakers, man does it sound tight. but i have a problem now. ever since i installed the headunit, when i start my car, it takes like 20 seconds b4 any of my gauges start to function. i mean they are all off. no odometer even, then they turn on, the odometer flashes a bunch of wierd looking numbers and then it shows my normal mileage. any body know whats up?
