Has antbody bought or tried an MTX Thunderform sub woofer box for the quad cabs. It looks pretty sleek but I'm not to sure about the material that they are using for the box. I am curious to know if it is better than MDF or Fiberglass. Any info would help

 

Mine sounds great but I've blown two Infinty subs so far

 

I have a pass and driver side q-logic and it sounds great. I think it would sound even better if I had the box rhino lined or line-x'ed. that would just make it more of a dense tighter sound...But Its nice!
