So, your advice is to go with 2 12's? SR said that one 15 would be a better setup. Since both sizes have the same rms and what not, is it at this point that the size/design of the box and port kick in? If I'm not mistaken, SR said I'd be better with the 15 because I'd have the proper cf needed for 1 15 as opposed to 2 12's. I just want the subs to hit hard and not sound like crap, seems as though I can achieve this from either 1 15" or 2 12", correct? How good/bad would 2 12's really sound with my space available? If the difference is slim to nill, then I won't be as concerned as I am now. Also, what do you guys think about 0 gauge wire?
