Bobby32 Posted July 1, 2010 Report Share Posted July 1, 2010 I've got a sprinter 100ah (65lbs) underhood, Big 3 in 1/0, 2 runs of power and 2 grounds, and a 134ah (or 120ah forgot..100lbs) in the back. I dont have a separate ground for the back- do I need to add one even though I have the ground runs from the front? Also what is the max length a ground run TO the amp can be? I'm thinking either: a. the amp is hella powerful and I need a new alt b. I need to add the ground c. the amp ground needs to be shorter. Thinking its A or B since it is a prototype Link to comment Share on other sites More sharing options...
