You're saying you are going to run a ground all the way to the front of the car? Good luck trying to start it... Or are you running just the positive to the front and grounding in the back?
nonono! you'll never get the car started. WAAAY too much resistance! Run AS SHORT of a ground as possible for best performance. Plenty of grounding spots in the trunk...If you want I can get some pics of mine later on.
Literally anywhere in the trunk is good, just look out where the gastank is...I chose this spot because i was able to drill a hole and get a bolt/locknut in there instead of using self tapping screws...much more reliable.
