You want to fuse (or use a circuit breaker) within 18" of each battery. If the wire shorts in the middle, you have to have protection (a fuse) near both batteries.

You should fuse every input/output going into the positive terminal of any battery within 18 inches. Including if you add a second one in the trunk.

what the hell do you have in your car that is causing a 350 amp draw?

i hope you have a high output alternator too.
