a man no matter what you do... the system will die down... a 2nd battery isnt always the case... the only bad part about that is that you can kill the alt. but in most case that isnt always the answer.. having 2 batterys is also making the alt work hard and trying to put back the Amp that you sucked out with the system.. just for a couple days out of the week charge the batterys.. but when charging start with the back battery. not the one in the front of the car... ill help you out if you have anymore question.. later man
