Description
Universal 6.5″ Solid Speaker Spacers 18mm ABS, Fits Most Vehicles.
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.
Unlike the waterproof MDF options in the Stinger range, the BKST9 uses solid ABS plastic construction offering excellent resistance to vibration, moisture, and heat while maintaining a lightweight, low-profile footprint. 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.
