MTX 3510-02 is great!
Crutchfield Customer Review (What's this?)
Ease of Use
The price is low for the quality of this product. It's well constructed, very durable and produces bass with accuracy. I replaced a Kicker Comp and the difference is rather noticeable. The MTX is made of better material. The sound quality is better than the Kicker and the price is better given the upgrade in performance the MTX provides. Oh yeah, easy installation and doesn't have to juvenile look that the Kicker Comp subs have.
Pros: All of the things you'd want from a sub (as mentioned above) including a fantastic price!
