I just bought 2 12' Kicker CompVX and 1800 watt Kenwood amp. But now i am stuck on what kind of box to get. I want it to be loud so people can turn their heads. Or at least i want to full effect of my subs. And I listen to rap. www.supercrewsound.com/commerce/product.jsp?prodId=345&catId=16 ^^^^^^^^^^^^This looks like it would be cool to put in and fit great, but would it be enough power? My trunk has bumps on the bottom back sides from the tires so i really can't fit a big box all the way back. i can put one up more close though. Do i get an sealed or ported? The guy at best buy told me not to get ported cause my seats don't fold down? but i heard ported was much louder. or what is the custom box that is made for my speaker? Last thing. are ban pass subs any good? Someone please help me. I am confused!! I know this is a lot but will someone please help me. im a newbie at it.
