These subwoofers are incredibly smooth sounding considering the price. I have 2 of these in the Sonic vented box powered by a Infinity 1600a and they sound great in my Mazda 3. They certainly are not incredibly loud, but they are loud enough, while still maintaining the sound quality. If you are looking for something that won't eat up too much space I would definately recommend these.

Basically I needed to downsize the bass on my rhd 93 mr2 because I had an orion 12 that took up mad space in the whip and because of the complaints, the overkill inaccurate bass and the waste of space I was thinking about an 8" sub. Because of my prior experience with jbl amps i knew this looked good, and boy this thing is not even even broken in and it hits almost all types of bass hard excluding the extremely low frequency's, shes running at 220rms with a Cerwin Vega sx220.2 and matched to the 7" bd small truck box.

December 6, 2011 AWESOME SUB!

I definitly recommend this sub. I did not have a lot of room for a large box in my show car. At first I was skeptical about the size. After building my own sealed box and stuffing it with poly foam, it sounds like i have a whole trunk full of subs. I have had good luck with JBL in the past, and this sub definitly did not disappoint me.

I am very happy with this sub. I'm running mine in a 0.4 cubic foot sealed box and she shakes the rearview mirror on 150 watts. I would recommend this to anyone who wants high quality bass in their vehicle, but doesn't have a lot of room for a big box.
