Overview
The Kicker 49L7X151 is a 15 inch subwoofer driver from the L7X line, rated to handle up to 4000 watts and built for box mounting into a custom enclosure rather than use on its own. Terminal wiring connects it to an amplifier.
This is a bare driver, not a finished speaker system, so a properly sized enclosure is required before it produces sound. Kicker's L7X series is known for square frame subwoofers that can fit tighter mounting depths than round drivers of the same nominal size. At 15.5 x 17.5 x 17.5 inches, plan the enclosure cutout and box volume around the driver's footprint before ordering.
- 15 inch driver, box mount design
- 4000W rated power handling
- Terminal connectivity
- Kicker L7X driver technology
Who it's for
Buyers who are building or upgrading a subwoofer box and want a single high power 15 inch driver rather than a pre-loaded enclosure. Not a fit for anyone who wants a subwoofer that works straight out of the box.
Pros and cons
- Rated for high power handling up to 4000W
- Square L7X frame can suit tighter mounting spaces
- Terminal wiring for straightforward amp hookup
- Requires a separate enclosure, not sold as a complete system
- No amplifier included
Performance notes
Power handling is rated to 4000 watts, which points to use with a matched high output amplifier rather than a low powered head unit. Terminal connections handle wiring to the amp, and because this is a box mount driver, its actual output depends heavily on the volume and tuning of the enclosure it goes into.
