Ok, so this is the last thing i have to do to my system to have it "functional". I still have to put all the stinkin' trim back on . I plan on routing the 4 awg power cable along the frame. Don't argue the point of a hole in the firewall and such, I'm just not going to do it.

The only easy routing i see puts the cable about 4 inches from the exhaust manifold and i can't find anyone who sells heat reflective sheathing. I'd rather not bake the cable. [img]graemlins/.gif[/img] Is there an easier way that i'm just not seeing? Keep in mind that i'm not necessarily looking for "stealth" or "cool factor". I just need to get from point A to point B without: a) hassle, b) much current loss and most importantly, c) anything melted. [img]graemlins/.gif[/img]

Check with your local semitruck parts stores. I've gotten some of that reflective wire wrap stuff from our local freight liner dealer.

They offer some stuff that is just a tube, and some of the bigger stuff has snaps every few inches... Hopefully this helps.

Seem's To Me That At Some Point, Your Going To Have To Drill a Hole To Pass The Cable Thru To The Amp Anyways. Mine Runs From The Battery, Along The Same Route As The AC Lines, Then I Removed The Top 2 Of Those Black Plugs That Hold The Firewall Deadner On And Replaced Them With With 2 Of The Newer GM Style Deadner Plugs That Have a Hook On Them. Ran The Cable Thru The Hooks, Over To An Area By The Steering Column, Drilled a Hole, Pushed In a Rubber Grommet, Ran The Cable Thru The Firewall And Down The Kick Panels To The Trunk. The Cable Is Wrapped With Wire Loom In The Engine Compartment To Protect From Heat But It's Nowhere Near The Exhaust. Also, There's No Cable "Under The Car" That's Being Exposed To The Weather Or Any Other Objects Under The Car. It Was Simple And Only Took About An Hour To Run!.....Mike

Well, the local Chevy shop in Tx City doesn't carry the heat reflective wire wrap, so i just thought of a good plan. Right now at work, one of our contractors is insulating 12 inch, 550 degree steam lines with mineral wool. I think i'll grab a little scrap, wrap/secure it around the cable, cover that with some aluminum foil (shiny side out) and put it in the engine bay as far away from the manifold as i can muster. This should keep most of the heat away from it. Maybe it'll work, maybe it won't. I'll give it a whirl tonight. [img]graemlins/.gif[/img]

Ok, well scratch that idea. Was talking to the IT guy here and showed him what i was thinking about and said i'd "fry the cable quicker than s***." Rats [img]graemlins/.gif[/img]

Told me (and showed me a way) to go inside the car. I would have to take that little plastic fender skirt off (inside the wheel well), drill a hole in the fender in the engine compartment, route between the skirt and fender, drill a hole at the bottom and front of the passenger door area and continue routing along my speaker wire.


Is there an easier way of doing this without taking off the skirt? I just want this thing done. [img]graemlins/4.gif[/img]

Holy crap, y'all are making this WAAAAY too complicated!

Go inside the car, on the passenger side. Pull back the carpet a little, as well as the rubber liner on the firewall. You should see (because it's pretty freaking big [img]smile.gif[/img] ) the pass-thru for the main wiring harness into the interior.

Pick a spot about 1" below it, and drill the hole you need (for 4 gauge wire, probably about 3/8" hole.....check on your grommets). Insert grommet, push power wire thru grommet (and route it up to the battery)....done!

If it takes you longer than an hour....well, you took too many beer breaks!

Just route the rest of the power wire along the floorpan to the trunk and on to your distribution block or amp or whatever.

Yeah, i know i made it more complicated than it really is. After finishing reading the myriad of search results, i settled on this method about an hour ago. I went out to the car, pulled the carpet back and BAM!, it is easy (not done yet, but looks easy [img]graemlins/.gif[/img] ). Sorry for making my "dumbass-ocity scale" reach about a 7 or so. I know what i'm doing tomorrow
