I got one. JL Audio Stealthbox, they make a version for powerstroke interiors. It takes the place of the guts of the console, and you just put the console shell over it. Can't really tell it's there, other than it raises the console about an inch.
Has a single 10" sub that faces downward, but it's a high priced JL sub, and put into a box that was designed and tuned for that interior. Sound, at least to me, is quite good. You'll get enough out of it to drown out that rap blaring cretin next to you in traffic. Green Grass and High Tides works very well for that...
Only other downside of this setup is, it's kinda pricey. Retails for $600, most of it is that expensive sub they put in. Got mine slightly used on ebay for $350. JL also makes a version that goes under the center seat for a 40/20/40 bench front seat. That person sitting on the center is going to really feel the music...
