[QUOTE="kross, post: 3275074, member: 577729"] You cannot use 8 gauge wire at any point with those two amps. You can use a single run of 4-gauge, and split it to two 4-gauge outputs for the amps, but you're getting very close to the current carrying limit of the single 4-gauge power wire to the battery. But since you will only be using 4-ohm loads on the zx650.4, you won't be putting out more than 480w if you run all four channels at full power. So that being said, you should really look into 1/0 gauge wire. But if you absolutely can't do it, you can use 4 gauge. The fuse that you will put in the wire, near the battery, will be rated around 125 amps. If you start drawing too much current from your amps than the wire can handle, the fuse will blow before the wire melts and starts a fire. But if the fuse ever does blow, DO NOT REPLACE IT WITH A BIGGER FUSE! Turn the amps down, or upgrade the wire! Only if you upgrade the wire, can you use a bigger fuse. Here's a distro block you can use: [URL="http://www.knukonceptz.com/productDetail.cfm?prodID=KNF-12"]http://www.knukonceptz.com/productDetail.cfm?prodID=KNF-12[/URL] By the way, you're putting together a pretty decent system. I seem to recall you saying your Pioneer headunit might need replacing, or am I remembering wrong? It's too hard to go back and read a thread while I've already started typing a reply... [/QUOTE]
