Alpine KTE-RS12G Grille for 12" RS-W12D4 and RS-W12D2 Subwoofers - Alpine's KTE-RS12G subwoofer grille protects your 12" RS-W12D4 and RS-W12D2 sub against damage in your trunk or cargo area. The metal mesh grille features a matte black powder-coated finish adds a clean, professional look to your installation. Simply remove the screws holding the subwoofer in place, place the included mounting tabs over the screw holes, and remount the sub with the screws included with the KTE-RS12G. An Alpine badge and a textured rubber screw cover add the finishing touches.
