Alpine KTE-RS12G 12-Inch R-Series Shallow Subwoofer Grille
Product overview:
The Alpine KTE-RS12G is a heavy-duty 12-inch protective grille specifically engineered for Alpine’s R-Series Shallow Subwoofers. If you've installed a space-saving shallow sub like the RS-W12D4 or RS-W12D2, this metal mesh cover is an essential accessory to keep your investment safe. It provides a robust physical barrier against shifting cargo, tools, or gear while maintaining a sleek, professional "factory-integrated" look in your vehicle.
Features
Seamless Connectivity
The KTE-RS12G is designed for a precise, integrated fit. Unlike universal grilles that may rattle or require complex modifications, this kit is made specifically for the frame of RS-Series shallow subs. It includes mounting hardware and tabs that fit directly over the subwoofer’s existing screw holes, ensuring a rock-solid connection that can handle the vibration of intense bass without mechanical noise.
Safety & Convenience
Protecting your high-performance audio shouldn't be a hassle. This grille features a black metal mesh construction that is strong enough to deflect impacts from heavy items in your trunk. For a clean finish, the kit includes a thick-textured rubber screw cover that snaps securely into place, hiding the mounting hardware and providing a smooth surface that won't snag on cargo or clothing.
Enhanced Audio & Ambiance
Even with its heavy-duty build, the KTE-RS12G is completely acoustically transparent. The mesh pattern allows the subwoofer to move massive amounts of air freely, ensuring your bass remains deep and distortion-free. Visually, the matte black powder-coated finish and included Alpine logo badge add a premium technological ambiance to your trunk, turning a standard subwoofer into a high-end focal point.
Fine Tune Your Sound
The KTE-RS12G uses an EZ Change twist-lock design (for the logo/finish plate) and a low-profile mount that adds approximately 1 inch to the mounting height. This allows you to "fine-tune" your enclosure placement in tight spaces—like under a seat or in a slim truck box—without sacrificing safety. It is the final piece of the puzzle for a professional-grade, shallow-mount audio system that looks as good as it sounds.
