usualy, caps are not needed for systems until you hit the 1000watt area. what kind of amp are you using? some amps draw a huge amount of current from the battery, and some dont. i am running about a 1000 watts from my sub amp alone (but there is a small cap in my amp) and my headlights hardly dim at all. im not an expert or anything, maybe there is something wrong with the alternator.
