I run stock batt and a c&d. Just don't play while car is off and your good

The only issue is that if the car were to sit for an extended period of time the larger (C&D) would eventually drain the smaller, maybe enough for you not to start you car. As long as it doesn't sit for an obscene amount of time you will be completely fine.

If you buy an isolator you can play when your car is off.
