i've got to hook up my subwoofer, got the RCA outs all connected to the amp, however, i dont know what size of wire to use for the other connection to the amp. i'll be running 300 watts to a JL 12w3v2 (d4). anyone have any suggestions? thanks

 

i think if you keep it under like 16 or 18 ft long, you can use 8 gauge. but to be 100% sure, run 4 gauge. but 8 should be fine.
