thenewguy16 Unregistered guest | 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 |

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. |

thenewguy16 Unregistered guest | 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? |
