Gregggg Posted August 3, 2009 Report Posted August 3, 2009 Just curious, why do people even bother buying a long strand of 1/0 gauge and wiring the neg to neg if they don't need it?

Dr. Johnson Posted August 3, 2009 Report Posted August 3, 2009 Because they are told that it is needed. When you get into chasing .1 of a db it might make a difference but for the average person it is not a significant increase that would make it worth the expense, hassle or time it takes to do it. That is just my 2 pennies though. Quote
Blazerbass Posted August 3, 2009 Report Posted August 3, 2009 so running + from front batt to + on rear batt just works? then ground the rear batt? Quote http://www.secondskinaudio.com/
