Where can i get the wire from? and how much does it normally cost for a feet?
add one more feet for slack and convenience to the actual or guess length that u come up with. thanks guys. :flash:
I've been researching this and plan to do the job in the next month or so. Like Mike said, use at least 4 gauge wire. It seems that 2 gauge is an oddball size; use 1/0 as its cheaper (from what I've seen). My only reference on length is OE BMW M3 + leads are 16 ft. Seems a bit long though.
You should only need one long piece for the + cable. Run the - cable to a convenient ground in the trunk (strut mount bolts?). Check Ebay for wire in Consumer Electronics/Car Audio & Electronics/Audio Components/Wires, Cables, etc. You can also find cable connectors, distribution blocks and fuses.
The following closed aution was for 4 gauge at $.99/ft + $5 shipping. I haven't checked locally to see how that total compares. You can also use welding cable, but again I haven't researched prices.

Have you figured out how to secure the battery yet? I'm ruling out the battery boxes from Summit Racing, JEGS, etc. due to price. I wonder if the battery tray from the engine compartment can be bolted or welded to the trunk floor. I've got to remove some acid corrosion this weekend and will look to see if it might work.
Let me know how your install goes.
