how do i know if i need a capacitor?

I would run one. I always have and prolly always will. It wont hurt anything lol. As for draining the battery with out it unless your running a massive setup thats not gonna happen. Even then a Cap wouldnt solve that problem.

Now im not an expert on this so other members correct me if im wrong but me and my friends did a few systems in our high school rides so I know a little bit about it. I think some one already said this but it was explained to me like this.. a capacitor is basically storage for the extra power when it is needed ( i.e. a deep bass line) with out a cap you may see lights dimming with the bass . I would say try with/out for a week or 2 and see what happens if you notice dash lights dimming out during allot of the bass hits add one to your set up.
