It thumps!

The following review is for P-XW1221SHP, which is a part of the bundle you are viewing.

First let me say this thing is bigger than I expected. And heavy! Definitely a solid well built piece. Great sound and was easy to set up. Just don’t be like me and expect it to be smallish. Lol It was installed in a 99 Camaro and I thought I was going to have to lose my rear seat to it. My installer got it to work in the hatch area though. If you’re looking to up your bass you can’t go wrong with this. You won’t hear it blocks away but we heard it in the store while it was across the parking lot at O’Reilly Auto Parts. It will vibrate your chest, your mirrors and anything near it with ease.
