About This Item
Maximize the bass output from your 10” underseat subwoofer enclosure for select trucks and other vehicles with this add-on extension port. The TXTRB10BB adds an extra 6dB bass to your 10” loaded underseat subwoofer enclosure (TXTRB10), doubling the output without having to add a second subwoofer. This optional module is built tough with a weather-resistant design to allow long-lasting use in rugged conditions.
