Input:
The basslink is a great powered sub for filling out the lows that doesn't take up too much space. I would recommend this to anyone who finds that they are missing the bottom end. Easy install and multiple mounting positions add to the package.

If you're looking for street shaking, neighbor angering, competition level bass then keep looking. This is for those concerned with sound quality only.
