na mohsin that not dual 8 guage wire, its dual 6 guage, :P.
P.s only 2/3 big 3s done. Alternator to battery not done. There was sum problem in fixing the terminals there, could accomodate 4 terminals at one bolt, so he advise me not to.
keeping in mind just under 1000rms, i think dual 6 guage is thicker that 4 guage plus this aint desi wire, proper imported one 300rs meter or so.
Anyways big 3 with 0 guage coming soon a to z :). this was a guzara thing i did arnd 3 months back
