When I pull up to a stoplight my voltage will stay at 13.6 and drop very badly.  So I've come to the conclusion I need another battery. We'll here's  the thing. I have an advanced auto autocraft gold battery rated at 800 cca. Would that work and if so is it ok because I believe that battery would give off some kind of gas in the sealed environment in my trunk.  Also  how do I run that battery do I have to make a second 0 guage run or what?And just incase my system is 2 12 inch pioneer subs. Pushing 500 RMS. In a custom ported box that I made.</blockquote>
