A very good set of shocks/struts at a great price, stiffer and better made than oem. Smooth ride without harsh jolting. Concrete Tile Proof

Poor Fuel Economy

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.

They are priced well, and they freaking POUND!

None. You just have to be smarter than the speakers.

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. I still have the kickers in a ported box, but I am now pushing them with a JL audio G1700 series monoblock amp. And they hit like you wouldnt believe. I would recommend these speakers to anyone! You can't go wrong. Kicker kicks some serious a_ _!

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)
I have a Dual 2 din dvd,Clarion 746 eq, P3002 (PUNCH) amp bridge to push the 12 Kickers a 4ch Power Acustic 400w pushing 4 6 1/2 panasonic 3 way 220w and a Punch Fanatic 6x9 200w 3 way. Everything on my car shakes and sound lose now. In just 2 days. I haved the same sound system for 3 years, but with the change to the vented box the bass sound 3 times more powerfull

Well it made a very big boom!!

After the big boom it fell apart.

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.

Great Bass

Makes my lights dim. Need to use a compositor.

This is awsome for a lot of bass, running a 1,000watt alpine amp. Looking forward to using a ported box!

Very strong bass.

May break windshield.

I have owned my 2 12" kickers for about 2 years now and they are still going strong. I have them in a 2002 Chevy Blazer. They are in a ported box that is made especially from kicker for these subs. I had them running off of a Mtx 600xd amp but wanted to see what they would do with more power so now they are hooked up to a Alpine 1000watt amp. They have shacken all the plastic molding loose in my car and have slightly cracked my rear window. For the money they are an awsome buy and you cant go wrong.
