I need your help people.
I had my car(99 accord lx sedan 4cyl 70k miles) into Circuit City to have my car audio taken out of my car. This was done Thursday. Two amps, all wiring and headunit. They returned the car back to stock.
This morning, the car will not start! I just jumped it and the car still will not start. It sounds as though everything is ok, but it still will not start.
Does anybody know what they could've done to my car?

I didn't drive the car since Thursday and now the car will not start.

I need your help asap.
Thanks!
Charles
