For the price, it being enclosed and the amps. This thing is great. I have it inside my 2002 f250 ext cab and its perfect. My friends who have 2 12s with ported boxes cant believe how much i paid for it. Everybody is impressed. They thought i paid atleasr $1000. Its not obnoxious. The bass is clear and smooth its honeslu perfect and exactly what i wanted. 3 of my friends are buying one now because theyre si impressed. And at $190 you cant beat it you really cant. If you were considering this im teling you do it. You will not be disappointed.
