Very nice speaker.

This is a very nice speaker if you realize it's small and ment for small areas. I used it in my tj and it fit well and sounds great.

Good Little Kicker!

I was looking for something to replace the stock sub in the center console of my 2004 Yukon Denali. I'm glad I went with this little Kicker sub. It is definitely four times louder than the stock that I had replaced. It fills the inside with more than enough bass to go with the mids and highs of the door speakers. Now, you won't hear it too much on the outside, which is fine with me because I just need enough to fill the inside and don't won't to annoy those around me on the outside (neighbors or other drivers). Remember, it is a little over 6.5 inches, so you won't get the bass that a ten or twelve inch sub will provide, but it will definitely give you an improvement over your stock 6 or 6.5 inch sub.

Overall, I'm happy with my purchase and would highly recommend this Kicker sub, especially if you are just wanting to fill the inside of the vehicle with bass without bother others on the outside.
