Order a battery relocation kit from Summit. Don't use car audio cable, it can't hold a candle to real battery cable when it comes to temperature, chemical resistance, or abrasion resistance. Welding cable is great cable. The Summit kit has good cable, and it's 2 gauge I believe so it's plenty large to start a four cylinder. Also comes with a battery box and some other stuff if I remember correctly. I've never bought one but I've known many dozens of people who have.
