Can everyone that is having this problem please tell me if they have stiffening caps on their stereo systems? Sometimes (especially when using cheap or faulty caps), small amounts of current may actually ‘leak’ in the cap slowly draining power over time. It took me 3 months and 2 dry cell batteries to figure this out. I’m using 2 caps that I had abused and found them to draw almost 1 amp.

I have a 1 farad Planet Audio Cap (with digital display)... but I was having these probems before I bought the cap. I actually thought it might help out a bit.

Its you battery it needs to be replaced its a problem with cold cranking amps the battery reacts differently in the cold then it does when its warm theres a lot more stress on it when its cold ie wh you had problems last winter it was good all summer now its getting cold again your having problems go look at some car batteries you will notice it has 2 ratings on it one for regular cranking amps and one for cold cranking amps
your battery is definalty the problem

I know about the cold cranking amps.. but since this problem started last winter, I've went through 3 batteries (exchanged, I didnt buy 3)... still think its DEFINITLY the battety?

[koncise]

Motomaster

I know, I know... but it should still work.

[maverick]

motomaster batteries can not handle vibration what so ever I can almost gauntee thats whats your problem especialay if you have a system

[koncise]

If that's true, then I guess that could very well be the problem.... especially since the battery's in the trunk with the subs.
