96Blazer Posted December 25, 2011 Report Posted December 25, 2011 I agree, Big 3 can be done for much cheaper then adding a second battery. I had the same issue in my first install in a Pontiac Sunfire and the "Big 3" upgrade cleared it all right up.

lilone71742 Posted March 9, 2012 Report Posted March 9, 2012 Yeah big 3 upgrade can run from $55-$200...depends on what you get. how would it cost that much??????all your doing is 2 grounds and one positive wire I spent close to 40. 10 ft of 0 gauge from knu konceptz (24 shipped) and about 10 on ring terminals. If you add in solder its about 45. Quote 2006 Chevy Trailblazer ~ KX 1200.1 ~ 2 Skar VVX 15" ~Big 3 upgrade ~ Pioneer AVH 4100 ~ 275 Amp Singer Alt ~ PRV 6.5 front doors~ 6000K Hids
