Product Overview

The Stinger BKST9 is a set of universal solid ABS plastic speaker spacers designed to enable the clean installation of aftermarket 6.5″ speakers into a wide range of vehicles where additional mounting depth or a level mounting surface is required. At 18mm thick and constructed from solid ABS plastic, these spacers provide a rigid, stable mounting platform for aftermarket 6.5″ speakers across cars, vans, utes, and SUVs.

As a universal product, these spacers are not vehicle-specific and are suited to any application where a 6.5″ speaker mounting solution requiring 18mm of additional depth is needed.
