Vented or sealed? You usually want to buy the subs first, and then the box so that the box can be built to spec. Sealed won't make that much of a difference, but u can go very wrong with a vented box not made to your specs.

 

ya the box is sealed..only reason i built it first was because i had old subs in it and it was the max that could fit in my trunk..

i saw an amp for a good price on ebay...it was a MA hardkore amp? are they anygood?..or soemthing to stay away from?
