THey were recommended for my subwoofer by Crutchfields at time of purchase. [ Bruce  Oct 26, 2016 ]
My box really doesn't move on the mat in my trunk, and even if I hit something, the box would still be trapped in the trunk and not go anywhere. But for $7, why wouldn't I mount it to prevent an unintentional movement in an emergency ? It just removes some doubt about where the box will be when I open the trunk if something happens or I decide to drive a little more spirited. [ Stephen  Oct 11, 2016 ]
I prefer the subwoofer in the P71 to remain stationary during cornering; These brackets will assist in that area. [ THOMAS  Aug 16, 2016 ]
Looks like a discrete but secure way to mount a subwoofer box. [ Barry  Jun 28, 2016 ]
