Does the starter crank? You mentioned theft system. Does that mean it has some sort of alarm system? I don't see how installing a stereo could have fried the theft deterrent system, but it's a vague possibility. Check to see if there is a starter interrupt on the alarm system. If so, disable, bypass or remove. Try jumping the starter solenoid to see if the engine will crank. Next, hot wire the coil to see if that allows the engine to start.
