I have two Optima batteries in the back of my Jeep they are for audio and the jeep itself. Ran a heavy gauge wire from the rear to the front with a 300 amp circuit breaker. I've been having issues popping the breaker while starting. Don't know if 300 is enough but I can seem to find one bigger. Can I run two 200 amp breakers in parallel?

I don't know what model Jeep you have, but 300 amps sounds a little much unless it's a big diesel. You can have your starter tested at the auto parts store for free.
