Get rid of the cap, get a batcap.

get some 1/0 and do the big 3. toss the cap as it's not doing a whole lot for you. if after the big 3 you are still having voltage issues then i would look into getting a deka or something

A cap would be a waste of your money. A battery might help band-aid the problem, but if you are experiencing significant voltage drop you need to 1) Do the Big 3 upgrade (search forums for how to do this) 2) Look into a h/o or reworked alternator that will put out significantly more than your stock.

Amazing advertising $$ at work. Uneducated (on a subject not in general) people are easy to sway with small amounts of well placed information.

What about just getting an optima yellow top? Would that be a better difference

Funny thing is, many places that sell caps (not all) are just as uneducated as the regular guy walking down the street. Companies bring in reps to talk about the benefits of their product lines, and the guy working for minimum wage or close to it at Best Buy eats up every word of it.

The alt output is 200amps
