I am not going to lie i was kinda iffy on them until recently when i was at Spring break nationals, and got a chance to sit in Serious Auto Sports Tahoe... He was running JLW.7, and they sounded great but they are way to expensive. As far as the kickers go, I personally have yet to here a setup that I have liked, and i have heard quite a few setups. Honestly like it was mentioned above for the price your going to pay for decent kickers there are so many other better brands in my opinion. As far as them getting loud I would agree until you go to a show or really start to get into car audio. When you see the big boys, such as the boys at spring break nationals I honestly do not recall any competing cars running kickers. They do however make very good amps, but once again they are to expensive for what they are.
