well i just installed my amp/subs using this method, I took my sweet time doing everything(2-3 hours total) but if I'd of stayed right with it it would have only taken around an 1-1 1/2 hours.

i was a skeptic that this would work but so far no problems, im gonna go test it out later and run some freq tests to make sure everythings fine

p.s. shawnkey thanks for the great write-up
