MTX"s compact X Thunderlink 210P powered subwoofer enclosure offers several mounting options so you can get plenty of boom without losing all your trunk or cargo space. The durable enclosure holds a 200-watt amplifier that"s fan-cooled for maximum efficiency. A 10" subwoofer throws down with thunderous MTX bass, while a 10" passive radiator adds extra depth. The amplifier turns itself on when it senses an incoming signal, so there"s no need for a remote turn-on switch. Mold your bass with built-in bass boost, crossover, gain, and phase shift adjustments — recessed controls keep your settings safe from unwanted disturbances. You also get a wired remote for fingertip bass control from the driver"s seat.
