    disto block is your best bet - it will make things a lot easier....

    you can do what I did - which was to run your single power line from the battery - fused within 18 inches of the positive terminal of course, to a distrobution block that has fusing as well....that way you have double protection, which would be a good idea to do anyways. I have a 300 amp fuse up front, then a 20 amp fuse at the disto block for teh computer and 2 80amp fuses for the amplifiers.
    Yeah, any time you split one wire into more, you should fuse for a few reasons. The main reason is if you have a nice 200A fuse at the battery, run 1/0 to the trunk, and split it into 2 4 gauge lines without refusing at the distro block, then if you get a short, you could get an electrical fire because the 4 gauge wouldnt be able to handle the 200A before the fuse pops! So you may think "well the amp has its own fuse", but definately fuse every time you make a new connection (aka after the battery, and after a split)

    Thanks for the info guys!

    I was planning on having just one fuse right after the battery positive but I guess I will put additional fuses after the disto-block to make sure!

    coming from someone who had a car fire due to an installers negligence...

    I fuse every chance i get...and I also don't let anyone else touch my car - that fire is really what drove me to get into installing on my own...lol

    fuses fused dist block

    So you are saying this would be the best way to go? BTW, on a inverter, do you run the black wire to the negative term on the battery?

    Like my schematic? the ........are to indicate nill, nada, nothing.
