Instead of pulling it all form your car's battery, it takes it from the capacitor making it easier on the battery. Then all the battery has to do is slowly "refill" the capacitor.
caps are pointless. they drain in one good bass note, and then have to recharge. so your actually using more power because the battery now has to supply the amp and recharge the cap. its a worthless piece of equipment. and as far as the box, your not going to be able to make a box to hold that 15 and have it where you want. that sub needs about 3 cubic feet. just build a box that takes up the whole trunk. you bought a big sub...use it. if you want that small of a box you might as well have bought a 10".
