View Full Version : Wire Problem

07-25-2005, 02:52 PM
I am in the process of building a fiberglass box for my dodge ram. I have completed the fiberglass and the box is almost finished. I have one slight problem. I am installing 2 audiobahn 12" compression piston subs dual voice coil. They take 1200 watts RMS each so I have 2 amps putting out 1200 watts RMS each. My first question is what gauge wire will I need to run for each sub. Also what gauge wire will I need to run from the battery to the amp. I will have to run the battery to amp wire about 10 feet. The amp to sub wires will run about 5 feet. I was told 1/0 was necessary. I have also heard suggestions on a 1.5 farad stiffening capacitor for each amp and getting a bigger alternator. I could really use some help on this. This will cost me a small fortune.

don't get A$$-raped on wire. www.knukonceptz.com or www.weldingsupply.com for heavy stuff.

x2 on the alt and no on the caps.
