[QUOTE="danielbea122, post: 8680123, member: 677445"] After the same drive I make every night with the amp ground to the frame I was at 13.8-13.9. With the amp ground to the second battery it was 12.7 last night after the same trip. I'm thinking maybe the original ground isn't very good so Im gonna try a different ground point with the amp ground to the battery. [/QUOTE]
