Product Research


Overview: The Alpine KTX-H12 Linking Kit lets you attach two Alpine R-SB12V or S-SB12V series loaded subwoofer enclosures (sold separately) in a side-by-side fashion.

Installation: The KTX-H12 includes a steel rear link-plate that bolts into pre-formed indentations in the back of the subwoofer enclosure, and attach via 4 pre-tapped screw holes using the provided hardware. Threaded alignment posts slide into pre-cut holes on the side of each enclosure, providing additional support. Two front port-braces lock the front of both enclosures together, while the front port-link covers the port-braces, adding attractive cosmetics to the front of the subwoofer assembly.

Compatibility: The Alpine KTX-H12 Linking Kit is designed specifically for mounting two R-SB12V or S-SB12V subwoofer enclosures together.
