[QUOTE="akheathen, post: 7440883, member: 629234"] idk where the "2k" came from, but the most i usually put through 4awg is 80-90a, but you could go 100-105 if you wanted... i suppose you could use 2 runs to go as high as the 125a peak, which would be the best without buying more wire, but i would go 2 runs of 2awg, or 3 runs of 4awg. actually, my buddy has that right now to his 2 jl1200/1's @ total 240a, which works fine. what happens usually when you exceed the ampacity is that the wire begins to blacken and force the power to travel through the core of each strand. this causes resistance to rise in the cable, and power to drop off by the time it reaches the amp. basically, it turns into a big resistor. of course, you can only run sustained current at levels that the alternator and alternator/engine cables can put out, and anything more than that is just draining the battery. another thing to think about. btw- we wired the 2 jl 13w6's up so that he is only pushing 600per daily, since are tahoes only holster a 165a stock alternator.
