Ugh, I ended up doing 3 runs of 16ga to each terminal leading from the subwoofer to the amp. Tested it out and it seems to be running just fine. Now i just need to tune my amp to get it to stop being "laggy" on certain songs. I'm almost positive it's because the subsonic filter is set on 15hz and the low pass is set on 250 (Basically the min/max of each) and the bass gain is up at around +12...
