I run 12g AudioPipe wire to my front 6.5's from the trunk and the same wires in 10g from my amp to my 6x9's in the rear deck. I would never run less than 12g or 10g to any subs, no matter the length. I'm just a firm believer in less resistance equals better efficiency. If I ever had a huge 10,000+ watt system with a wall of 15's or something crazy I'd probably run 8g or even 4g speaker wires to the subs! The only thing that baffles ME about ANY speakers is the fact that no matter how fat your speaker wires are from your amp to the speakers, the speakers always seem to use that itty bitty 22g wire from the terminals! That was what impressed me when I just found some Nakamichi NSWZ1206D4 12's that handle 3,600 watts max (allegedly) was they use a RIBBON wire from the terminals! THAT impressed me! What is steering me away from buying them is they only go down to 45Hz, which to me isn't low enough. I gotta get down in the 20Hz range or they just don't seem like subs. But yeah, I'm running 10g to my rear speakers and 12g to the fronts. I really doubt I can hear the difference, and I doubt you will either.
