I had a 2001 chrysler sebring with the battery in the wheel well and I think I ran some 0 gauge up to that post from the battery and then from there to my system.
I have a mk 3 brahma custom built by SPL audio on here. Its pretty sweet but I am going to want 200 plus shipping for it. Im going to make a for sale thread for it soon and SPL audio should be able to tell you everything about it.
