Im not sure what kind of capacitor I should get for my sound system in my car?

Check these sites out...it is a good reference. http://www.bcae1.com/ http://www.rockfordfosgate.com/rftech/rftech.asp http://www.caraudio.com/forum/showthread.php?t=198477 http://www.termpro.com/articles/articles.html#How - Also check this out http://www.youtube.com and all related videos...Look for the guy in the blue collared shirt. Type “car audio systems” in the search engine. He gives a lot of very good info. If your headlight dims with the bass notes, the “BIG 3” might work. If not an H.O. alternator will be needed, or else be prepared to pour a lot of $$$ for batteries. This site explains the "BIG 3" upgrades. http://forum.sounddomain.com/ubbthreads.php/ubb/showflat/Number/312025/page/1 I've designed my car for SQ (Sound Quality) not SPL (Sound Pressure Level) my imaging is very good. The bass sounds as if it is up front and my 12 inch sub (picture as shown) in the trunk. I LOVE how it all worked out.
