Sounds like you're running serious power back there, I can understand the need for the runs of cable. I'm a little more low-key //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gifive got 4 runs of 1/0 under the car the first pair i just ran thro two holes that were already there then the second pair and use a hole saw and ran the second pair thru. i took out the carpet in the back and the black plastic jack holder and just put the jack under the passenger seat towards the back since its got all the air bag stuff under there. when i had my 2 15s in there i just made the box sides extend a little more to make the box float over the batteries with my 2 12s just made a false floor
Lowes or Home Depot would have it, though you want the stuff that's called Carflex Liquidtight. There are other brands and variations out there, but that's the one you want.Where do you get that conduit or whatever it's called?
Not saying its a problem running inside, I just prefer to run the bulky stuff outside. And for less than 20 bucks for the Carflex, clamps, and fitting, it's a no-nobrainer for me.Why not just run the wire inside the cabin? I ran 2 runs of 2/0 on the inside of an '09 Escape w/ no problems.
