Caps are worthless imo. What is the amperage of your stock alternator? I'm running ~1000w rms and i have no problems whatsoever. My alt is also 117amps stock //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
sell the cap for a fuse holder and go buy some 1/0 and do the big three and definately look into replacing your batt ASAP as well, then play that out, then decide weather or not you want to do the alt too
this was post in an old thread but is really useful al the people how sais cap are useless or a waste of money have never seen the electrical curve of a system with and without cap, the article explain it better
a cap isnt gonna do wat hes talking about if he doesnt have good enough alt or battery. If he just stay stock on his electrical system and adds a cap it isnt gonna do nothing caz he cant provide the power. and keep in mind that cap was providing enough power for milliseconds.
do big 3 then get a better battery then see how it goes or maybe just do big 3 and add a hc600
