[QUOTE="randomguy0o1, post: 8487073, member: 669377"] My question is basically this: what does the current look like(not actual LOOK) from the alternator to the first battery? Is it the same as from the second battery and to the amplifier? I want to run two batteries in parallel and try to not have to upgrade my wiring. I have 4 awg wire running from the battery. I don't acutally have a 2nd battery yet. The wire from the alternator is stock. I know that if I have one single battery, the 4 awg would burn up since it would be running the length of the car and be carrying around 150 amps (the fuse on the amplifier is 160a). What should I do? Do I have to upgrade to 0 awg? [/QUOTE]
