momma says that caps are the devil. just kidding.. well you don't need one. they are a temp. solution to a bigger problem. start by doing a search for the big three and do that. also look into 0 gauge wire for your amps. upgrade to a yellow top or something of the likes that is a deep cycle battery. that should help with most of your dimming issues. if still doing to look into an upgraded alt.

doesnt matter, u shouldnt even mix different subs let alone different sizes...a well put box with 2 12'' could out do all of that...sell it and focus on another design..

Caps are useless.

Let me put in it perspective. Regular Caps are 1 Farad, some are up to 10 Farad, but are extremely expensive.

A battery is about 10,000 Farads, I believe. Perhaps more.

So, what do you think is better?

Get a Yellowtop Battery under your trunk, do the big three. If your sh*t's still dimming, get a High Output alt..

I'm telling you, Caps are just pretty, that's it. The numbers they do are completely useless in comparison to a second battery, or better wiring.

Depends on your batt, alt, and size wire you used. If you have a lot of extra power to throw around, I don't see why not. But it puts a lot more strain on your alt constantly refilling that cap, and your battery(ies)

EDIT:: And for the record, more subs does not always = louder, or better sounding. It just means more. As said before, a properly built / set-up 12" system could outperform all 3 12"s, 2 10"s, and what? 2 15"s?
