Just to back up what Helotaxi said, not trying to ride his nuts.... The JL's are great SQ subs but aren't "loud" like a DC, Incriminator Audio, etc brand sub. If you want loud, you're probably needing another brand of sub. If you want really good, clean, super crisp lows with pretty good volume....JL, Soundstream, and old Phoenix Gold will do it. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif Most of the newer high output/SPL brands aren't good for SQ unless you're up in the $250+ range each.
