ey guys (sorry, don't really know if my topic belongs here
i have a 1300 watt system in my mini. i noticed that ALL lights kind of dim when i'm playing music at almost max level to max level. according to my installer, i should change my battery to a "deep-cycle" kind of battery which will eliminate the dimming of the lights under heavy electrical load. i also asked him about the alternator (if i have to change it) but he said that it was ok and that the battery will do the trick.
any thoughts on this? shouldn't a 2-farad cap be enough for the lights not to dim?
