Alpine KTX-EBKT Universal Subwoofer Mounting Bracket Product overview: The Alpine KTX-EBKT is a heavy-duty universal mounting kit designed to securely fasten your subwoofer enclosure to your vehicle’s floor, trunk, or walls. A sliding sub box is not only a nuisance but can be a serious safety hazard in the event of an accident. This all-inclusive kit is built with 7mm powder-coated steel, providing a rock-solid foundation that prevents your enclosure from moving, ensuring both the safety of your gear and the consistency of your audio performance. Features Seamless Connectivity The KTX-EBKT is engineered for "no-drill" integration with many of Alpine's modern enclosures. It is fully compatible with PrismaLink™ and R-Series Shallow Enclosures, utilizing pre-drilled holes for a direct bolt-on setup. For other Alpine Halo or universal third-party enclosures, the kit remains highly versatile; while some drilling may be required, the brackets are designed to accommodate a wide variety of mounting surfaces and box styles. Safety & Convenience Security is the primary focus of this kit. By anchoring your subwoofer enclosure, you eliminate the risk of it becoming a projectile during sudden stops or sharp turns. The kit is truly all-inclusive, arriving with everything from the heavy-duty brackets to a 4mm hex wrench and various lengths of tapping screws. This convenience means you won't have to make extra trips to the hardware store to find specialized fasteners for your install. Enhanced Audio & Ambiance Beyond safety, the KTX-EBKT actually improves your bass experience. By firmly securing the enclosure, it minimizes "baffle movement" during high-excursion playback. This reduces the diffraction of sound waves and unwanted vibrations, resulting in harder-hitting, cleaner bass and a more premium audio ambiance. Your music will sound more controlled and impactful because the energy is directed into the cabin rather than being wasted on moving the box. Fine Tune Your Sound The brackets are finished in a matte black powder coat, allowing them to blend seamlessly into your trunk’s interior for a professional, "factory" look. With 7mm thick steel construction, they are far more durable than standard L-brackets found at local hardware stores. This robust design allows you to "fine-tune" your enclosure’s placement for optimal acoustics, knowing that once it is bolted down, it will stay exactly where you want it regardless of your driving style.
