[QUOTE="bbeljefe, post: 8150665, member: 655960"] When the car is running, the alternator supplies most of the current used. Batteries are there to help a large audio system, not run it. As was said already, if you're going to listen with the vehicle not running often, then use an isolator. If not, don't worry about it. The only thing the isolator is going to do is prevent the audio system from using the main battery for power, so consider that before you buy one. And also, ditch the circuit breaker and put a fuse on the system. Circuit breakers often don't trip fast enough during a low resistance short and can cause damage to the electrical system and/or your amplifiers. If you want to keep the CB as a quick disconnect, then that's fine but again... fuse that power line. [/QUOTE]
