I found 4 gauge speaker cable from an audio shop (this is the same size as the factory battery cable if I'm not mistaken). It's very high quality. 0 gauge is just too expensive and 2 gauge is very hard to find. I got 30 feet of 4 gauge for just under $30. I've done some research and a lot of guys run 4 gauge with no issues. I have no extra electronics at all, just stock accessories and that's it, so it should be fine. Going to get the fuse shortly, and start the relocation.

 

fleamarket , I bought mine on nebraska fleamarket .I believe I paid $40
0 gauge 15' red , 3' black wire

 

That's not too bad. I'm pretty sure 4 gauge will work since the car only sees the highest amperage at startup. I'm wondering if anyone else has used 4 gauge audio cable for battery relocation. There seems to be a lot of guys running it with no issues at all; however, everyone on the forums states it's too small. I understand that the car is going to pull a bit more amps due to resistance from the length of the wire, but is 2 or 0 gauge really necessary?
