For the price this thing is awesome. I have one in a ported box in my crown vic and it sounds great. Don't expect extreme bass from one of these but it will still hit hard. The speaker grill it comes with is cool too.

I bought these subs for a Honda Prelude but never got around to installing it because I replaced it with the Type X 12, BUT I sold them to a good friend of mine to puy in his car and lemme say... WOW I actually didnt expect them to perform the way the did because of the price, but man was I wrong! He since then has put them in a truck and they are still going strong and sounding phenomenal...after 5 YEARS!!!

This is a great buy and bang for your buck if you dont wana invest a lot as extra batts or HO alts etc., and just looking for a nice, clean sounding system, look no further, Alpine delivers!!
