Summary: I have one 12 Comp VR in a ported box in the back seat of my 03 Silverado and it vibrates my truck and those around it. This sub hits every pitch of bass i throw at it. It handles low bass with a smooth flowing vibration and will slam the hardest beats. Example, Lemonade by Gucci. Disgusting. this sub hits very clean, no distortion. The bass key will be all the way down and the sub still vibrates everything in the truck.
Summary: I have had these speakers for about three months, and at first I had them in a sealed box, with a crunch 1100 watt amp bridged to push them. And they straight pounded. Then I got greedy for more sound and put them into a porter box, without giving them time to adjust I pounded them until I blew one. The speaker failed because I was stupid. So I bought all new stuff.
Summary: I have this pair for 3 years on my 2002 Maxima.I haved for last 3 years on 2 small sealled boxes, and they sound ok. 2 days ago 10/22/2010,after some web research I build a vented box my self (16 1/2h x 16 1/2d x 36w). What a diference, I haved to admit, they sound almost as powerfull as my old Punch P2 15" (THAT SOME BODY TAKED WITH OUT PERMIT OUT OF MY CAR JA, JA)
Summary: I would never recommend nor will I purchase any product from this supplier. I felt violated that a company would take advantage of my well being, buy pushing this product on to me. It is no different than what the Germans did to the Jews.For now on I will study history with a passion so I do not fall into a trap like this again.
Summary: i bought 2 12 CVRs and they hit pretty hard, i have them hooked up to a mono channel 1000 kenwood amp to make the install easy for my lazy ass. i have a q-logic box that has a sealable port so when i feel like listening to rock i just seal it up, but the things hit so damn hard it doesnt really matter if i have it sealed when i listen to deep bass.
Summary: i just bought 2 of these and these hit harder than my friend 2 RF 12" HE2, and they even hit harder than my friend 2 JL's W3 15", and i only have bout 250 watts goin to them wit a 600watt Bazooka amp
Summary: When I first was looking around for subs I wasn't looking for a particular brand. After 1 look at these at my local audio store I decided I had to get me a pair of these. I made my own box exactly to Kickers suggestion and have a 1000 watt Clarion amp pushing these babies at 450 x 2 @ 2 ohms. I have not heard ANY DISTORTION. Whoever has some, needs a better amp!!!!!
Summary: i''''d just like to say that i am now a Kicker fan. I have been through Orion, JL Audio and now Kicker. My 2 comp vr''''s (dual 4 ohm) are the best subs for the money that i have heard in a long time. They play very deep and have pretty good SQ. I built my box from the specs that came with the subs, and they sound great.
I would suggest about 200 watts rms to each sub and ALOT of sound dampening in your trunk.
