i have a NSB90 in the trunk, and i wired it this way.
power cable from the alternator, to the inline fuse up front, inline fuse up front all the way to the trunk to another inline fuse, inline fuse to battery +, battery + to ANOTHER inline fuse, and inline fuse to the amp. thus the battery is being charge from the alternator and no strain on the battery up front. Also, there 3 protective inline fuse holders, one in the front, one before the power wire gets to the battery, and one before the battery goes to the amp. simple enough.
