Sounds lke you could possibly have a weak electrical system, like a weak alternator, or battery. That when there'* a big draw on the system from your stereo, you're electrical system can't get enough power to the ignition system.

Just my thoughts.

I'll agree along with the guys.

Advance Auto and Autozone will tyipcially test both battery and alternator in the car for free. This would be a good start. Then probably checking the grounds etc.
