I have a question about 3 batteries installed. Do I need the an additional 300 amp circuit breaker as well as 2 other 300 amp anl fuses for my 3rd battery? I ask this because my 0 gauge wire got hot and melted my plastic cover on the end. I installed a 3rd battery because of new speakers I installed which were 4 audiopipe 10's which are peak 700 watts but 350 rms hooked up to a power acoustik 1600 watt rms amp. I dont want my car to catch fire so I figured I would ask some experts on here. basically should I do the same exact thing as I did when I ran my 2nd battery to the 3rd?
