The Kicker CVX122 BOOMS. Absolutely slams in my boat in a sealed enclosure. I'd say it's not the most musical sub out there, but it has excellent slam if that's what you're after. Good stuff. Great build quality.

My experience with Sonic Electronix was great. I installed the unit into my box hooked it up and it worked perfect. A lot goes into making your subwoofer sound great. Your audio supply, your power in, your amp, the wiring. For the most part I would rate this sub as a great buy. I have not had a chance to fully use it to its max as my in-dash was recently stolen.

These are awesome i bought the discontinued model a year ago, they were only 175 a piece. These are have SQ and can handle tons of power!!!! i have both of these running off of a JBL GTO 14001 amp its a monster amp!! And these things handle all the power nicely!!!! i have burnt out subs before in the past the way i like to play my rap music, but these seem to handle it very nicely, i don't really agree with the price of the newest model of these subs they seemed to increase of 100 dollars but all of the specs have stayed the same, there is no reason anyone should get the square L7's these handle just about the same amount of power and have better sq, these subs are basically the L7 just in a round version therefor due to the round factor the sound quality is better.... thank you kicker you have pleased me.
