ok thats good to hear, because the manual says 4 or 8 but a guy at an audio shop said i should run 4 gauge. but who knows, probably just trying to make more money, and those 4 gauges are harder to run because of their thickness
4ga can carry more current, and the size of wire is based on current and distance. 4ga would also allow you to later add a distribution block and a second amplifier. 8ga is going to be pretty much close to it's limit with that one amp. He was probably just erring on the side of caution. here's a chart that'll help: http://www.the12volt.com/info/recwirsz.asp
your amp is 300wRMS @ 2 ohms (total) figure since it's class AB, that'll be 35A of current draw at full output. By the above chart, 8ga is sufficient for up to about 10 feet.
ok i bought a 4 gauge wiring kit yesturday, came with the 4 gauge wire with a distributor and a 8 gauge wire. It came with an 100A fuse. will this work?
