High power for your subwoofer system Focal's FDP 1.900V2 mono subwoofer amplifier can deliver up to 850 watts RMS to your subwoofer — providing the low-frequency foundation you need for your vehicle's high-powered audio system. The amp's Class D technology delivers this big-league power from a chassis that's smaller than a 2" stack of printer paper. The extensive and versatile filter section lets you optimize the tone and performance for a wide variety of subwoofers, while a variable bass boost and adjustable phase focus the bass in your vehicle. The speaker-level inputs and auto turn-on let you connect this amp to almost any car stereo, even a factory radio. Remote control and clip light Focal includes a wired remote bass level controller so you can tweak your bass from song to song from your front seat. This remote also features an LED clip light that'll let you know if you're overloading the amp.
