Alpine KTX-H12 Linking Kit

Alpine KTX-H12 Halo Sub Linking Bracket

Product overview:

The Alpine KTX-H12 is a specialized linking kit designed to combine two single 12-inch Alpine Halo preloaded subwoofer enclosures into a unified dual-enclosure system. Featuring Alpine’s innovative ProLink™ technology, this kit provides the heavy-duty hardware necessary to "double the bass" while maintaining a clean, professional appearance. It is the perfect solution for users who want to expand their system's output without replacing their existing 12-inch Halo sub.

Features

Seamless Connectivity

The KTX-H12 utilizes ProLink™ technology to bridge two individual enclosures together. It is specifically engineered to fit the S-SB12V (S-Series) and R-SB12V (R-Series) 12-inch Alpine Halo preloaded boxes. The kit provides a direct physical link that ensures both enclosures act as a single, rigid unit, preventing them from shifting independently during high-output playback.

Safety & Convenience

Built for maximum durability, the kit includes a heavy-duty steel rear link bracket and a heavy-duty steel front port link brace. These components reinforce the connection points between the two boxes, providing a sturdy installation that can handle the massive vibration of dual 12-inch subwoofers. All necessary mounting hardware is included, making the transition to a dual-sub setup a simple "bolt-on" process.

Enhanced Audio & Ambiance

By linking two 12-inch enclosures, you significantly increase your system's surface area and air displacement, leading to a massive jump in sound pressure level (SPL) and low-end impact. The KTX-H12 shares the same clean silver finish as the Halo enclosures and features a premium stainless steel Alpine badge on the top bracket, adding a sophisticated, custom-shop ambiance to your vehicle's trunk.

Fine Tune Your Sound

This linking kit offers the ultimate flexibility in system design. It allows you to "fine-tune" your budget and power needs by starting with a single 12-inch sub and adding a second one later. The port link bracing is precision-cut to follow the exact outline of the enclosure ports, ensuring that the structural integrity and airflow of the boxes remain optimized for the best possible acoustic performance.
