On that run up the gunnel to the tower did you consider techflex instead of the split loom? Split loom (IME and all that) gets brittle and cracks and looks sorta ghetto too. you could get 3/8" techflex here for cheap
Not tryin' to be a hater, and I'll bet the system rox! Hope to have pics of my winter rebuild up before the weekend's out. I'm runnin' the kicker amps too.
