??06 crew cab sub box - which is better??

[1997 z71]

I have a 2006 chevy k1500 crew cab and I am going to put a sub box behind the rear seat. I was wondering which sounded better, a wooden box($120) or a mtx plastic box($270)?
any suggestion would be appreciated.

A custom built one out of 3/4" mdf with a 1.5" mdf baffle and extra bracing tuned correctly to your sub and fitted to your vehicle sounds best.

I agree, and should be less then that mtx box
