Do i need a capacitor?
I just bought a phoenix gold xenon x100.4 100 watts per channel amp and infinity kappa 2 way 60.5CS 6.5 inch components for the front and 6.5 inch kappa 65.3i coaxles for the back. I also have 2 JL W3 D4s being powered by another phoenix gold amp, though im not sure of the power rating on that one. I haven't installed anything yet, but I'm wondering if i will need a capacitor, or a beefed up alternator, or a second battery, or all of the above? I also might be getting a dvd player in the dash in the future. Thanks!!

When I was shopping for my amp (5 channel) and sub (haven't done speakers yet), my shop told me that an Optima Yellow Top would be a better purchase than a cap. They also said that a lot of caps (even some expensive ones) don't really do what they claim. Whether you need one could also depend on your current level of hearing loss or future goals in hearing loss.

caps are great, if nothing else, they'll keep your lights from dimming during loud bass notes. I've personally tried both generic (non-branded) and lightning audio. I was equally please with both. I ran 2x 0.75 farad caps that I picked up for like $50 at an electronic store and it worked great for me. Now I'm running a 1.0 name brand cap and it seems about the same. Granted either is an improvement over none
