Great bass boost. Small footprint, easy to wire in + the remote control is an excellent way to adjust the settings on the fly.

Great subwoofer, great sound base. I would recommend more mounts especially if someone wants to mount it in their boot on the side like I needed to. Overall great budget subwoofer.
