costs 87 cents per foot at lowes
I hope you didn't think I was a naysayer .

I just said 0 gauge ftw as a lil funny pissing contest. However, I beat you out in price. 0 cents per foot from my audio sponsor back in the day, hehehe.

just run wire shielding for the part in the engine bay

Dean, Kenrik, did you guys ever have a problem with the big fuse/breaker? If it was sized too small, it would blow under high load conditions. Someone asked what size fuse to use, and I added up all the current drawn from the lights, heater fan, starter, etc and suggsted a fuse a bit larger. How did you guys come up with 100A or 200A?

i bought 15ft of welder 2ga wire @ ace hardware(expensive, really), ran through ecu plug same way as you did, bought autozone box and i even have an optima(had a cheap battery before gettin the optima), but i do need to get 1 of those breakers, also i unplugged 1 of the rubber circles on the pass side, which down of it has a bolt i grounded the battery to, it works great and has been for more than a month.

that 2ga welder wire is good stuff

I have never flipped the breaker in my car. I didn't do any math to find out what breaker to use, I just took a suggestion and bought one.

OK. As an electrician, the wire that Kenrik ran will do just fine. If you have any worries about it just wrap it in the high temperature plastic wrapping everyone uses aroung all wires in the engine bay. Also, AWG #2 wire, like what Kenrik used, is good for 250-300 AC amps. Which in no way is higher then what your starter is pulling (in DC). #2 wire like that is made to handle HIGH heats considering the amount of amps that it can handle.Kenrik, don't worry about your wire. ALSO, I hate to say it but, the best thing to use to hook up your old wires to the new wire is to use a non-fuseable wire block. Just get one to handle your input wire and your output wires. Also, that last time I checked, you don't need a fuse inbetween the battery and the starter. If you did everything correctly, you should have no problems. And if you are gonna use one, then get atleast a 200amp'er. Just my 2 cents.

When I did this I ran the ground under the car and directly bolted it to the frame of the car, then covered everything so water wouldn't get to it. Hasn't shown any problems for me.

If you don't use a fuse, what happens if you get a short somewhere in the 15 feet of wire running from the front to the back? I wouldn't be surprised if that happened. I have shorted my optima before when I was installing it. Not fun. I thought I was gonna die.

Dude, that's moronic. That's the same as not installing a roll cage in a rally car to protect the driver, because "If he did everything correctly", he would not be in a rollover wreck.

The relocation of a battery requires running 12+ feet of wire directly next to the frame of the car. Part of this run is under the carpet where it could be rubbed thin. Better safe than sorry.

HAHA if wires didnt chaffe i would be out of work, sometimes we rip a whole plane apart takes a week to find a chaffed wire in a bundle, its like hell on earth.

i bought the summit racing relocation kit.

another alternative for the positive cable is cabling from a welder. (which honestly would probably work the best anyway)
I bought a Moroso Blue vented box to install my Sears Die Hard Gold in the trunk I am considering cables and battery plate to complete the job I want to know what you think of the Summit batter relocation kit, I realize it is only a 2gauge cable but I want to know how it worked and if you had any starting problems or any other electrical problems using their equipment. Their price is only $39.99 and most others prices are at least double and I want to make a decision soon so I appreciate your input thanks, Neil.
