Here is the last setup that was in it... https://www.youtube.com/watch?v=qGsBNHaS_yk https://www.youtube.com/watch?v=JD3aq0Nh8pQ Now for the new setup.. Still not 100% where I'm going with this build, but its getting walled! The for sures are: 3 DC Power alts. 2 XS Power S3400 under the hood. 5 XS Power D3100 in the back to start, goal is 9 total. 2 Sundown SAZ-4500s powering subs for now (maybe 4 down the road with new woofers). 16 runs (8pos/8neg) front to back Audio Technix CCA 1/0, It was cheap, and for the price OFC wire wouldnt handle nearly as much current @ 200amps per run for CCA.
