Whoever said they would count they caps on their amp is retarded. No offense cause you're not a bass head like me. The real purpose of a capacitor is to relieve stress from the alternator. I know, I've replaced one due to my last system. 1400watts RMS 2 12" Audiobahns. Rock the block kinda bass. Anyway, the capacitor is a cheap alternative to a dry cell battery which are expensive.
I've been looking at getting two 12" Type R Alpines for a while now. The only problem is they are so dang expensive with an amp that would run them. The Type R's are rated 500-1000RMS so yes your 400watt amp is underpowering them. Yes underpowering is bad.
Other than that I like the setup except you would get much more bass out of this sub in a sealed box with the right dimensions. And to help your trunk rattle problem if you have it with one 12". Get the dynamat trunk kit. I installed mine myself and the trunk rattle was gone.

A capacitor has very little reserve (how much juice it can hold), causing more strain on your alternator. Especially stock electrical. An actual battery would do more good. What a capacitor has that a battery doesn't is speed. Thats why car audio batteries like Stinger, Kinetic and Powermaster are so benneficial. They have a larger reserve capacity and deliver juice much quicker than your typical battery and also recharge much quicker. There's also something called a Bat Cap. Its around 70% battery and 30% capacitor give or take depending on the model. It has less reserve than your average car audio battery, but it delivers quicker with less impedance rise and more amps.
