Factory audio does not work! HELP

[O.D. Showtime]

So here's my situation:

I have a 1996 Cobra w/ Mach 460 sound. When I purchased the car, it was equipped with aftermarket audio components (speakers, sub, amps, head unit, wiring...everything). I have all the factory equipment and re-installed it using factory Ford wiring (which was left in place during the aftermarket install). However, upon turning the ignition, only one speaker in the car works...and that's with the volume cranked all the way.

I've checked the fuses, which are fine. I've checked connections, which are also fine.

Could anyone provide insight into why the audio system is not functioning? And where is the ground on the car? I haven't checked that.

Thanks.
