Okay I have a Question.. Seems to me that every audio store i go to, they all sugest a differnt box. Well Would SOme one tell me the defference between the Boxes And if 10's or 12s or what not would sound better and hit harder in these boxes.. I have a 1600 watt 4 channel Pyramid Amp. I want to feel a back massage from these subs. I'v seen Before 10% product, 90% install. So what should i do. Im looking to spend about 250 - 300$ for my subs. What subs should i get, and what box.. I will probabaly make my own box to fix the subs.
