Sound Ordnance Sub fits in 2004 CC?

I'm looking to add some low end thump to my 2004 Crew Cab without spending much cash, and have recently been looking at the Sound Ordnance B-8P sub:

Sound Ordnance™ B-8P 80-watt powered bandpass subwoofer at Crutchfield.com

My question is would this fit behind the rear seat of a crew cab? If not, what are some suggestions for where to put this sub? Thanks!
