07 Tahoe sub enclosure question

Looking to see if any of the fellow forum'ers have any experience with this builder or at least type of sub-woofer enclosure? I am looking for something that goes under the middle row bench seats.  Curious how it sounds, how it works with the seats folded, etc.
 
Thanks in advance..

I bought my box from him and he builds a very good quality box....no problems at all.  My box is the one that goes between the 2nd row captains chairs.

TMW597 installed a JL Stealthbox sub which is made for the center console. Just another option to consider.

So basically people can't sit in the back then?
