Mine is an 8in kicker in a shallow enclosure, passenger floor, next to center console. Last time I posted a pic, I got ripped for it being "ghetto", lol!
Not at all ghetto and only slightly restricts side to side leg movement.
Powered by a 250w Sony Xplod, I'd swear it was a 10 if I didn't know better. Sounds great, drop in, and hassle free. Of course, I'd like to drop the sub into a more hidden custom enclosure, but as it isn't a problem, haven't gotten around to it. It's also just not a priority for me. I like good sound for road trips, but around town, the sound of the engine is just fine
Oh yeah...Sony Xplod HU, infinity 6.5's in the doors, infinity 3 ways up top, all four powered straight off of the 52w x 4 HU. Sound is amazing at 70mph with the top down

Say what you will, it's just fine with me
