Installed it this morning and am quite pleased. It's not the booming bass that you get from multiple subs in the back but it has a good amount of rumble to it. Plus it takes up a little more room than an amp. I'll take a photo and post it tomorrow. Now I've got to go around finding all the rattles and try and shut them up. As well as put some sound deadening in the trunk, I think that will help contain the bass in the car.
