Monoblock Class D Subwoofer Amplifier, 500 W x 1 @ 2 Ω / 250 W x 1 @ 4 Ω - 14.4V

Born to produce a whopping 500 watts into 2 ohms (14.4V, 1% THD), the RD500/1 amplifier was engineered to generate tons of pure subwoofer bliss from a sleek, ultra-compact chassis. The secret behind its power proficiency is our proprietary NexD switching technology, which delivers large amounts of power output with precise efficiency and ultra-low distortion.

For your convenience, the RD500/1s controls are located on top of the amplifier, beneath a protective cover, with all connections found along one side of its chassis. Signal processing features include a 12 dB / octave low-pass filter, with continuously variable frequency selection from 50-500 Hz, and a variable bass boost EQ. Dual-range, differential-balanced inputs are also on-hand, capable of accepting most input voltage levels. Automatic turn-on capability (via signal sensing or DC-offset sensing) is standard, along with a set of preamp outputs so you can easily pass signals to another amplifier.

The RD500/1 is also equipped with an onboard LED-clipping indicator. This all-new, innovative feature lets you easily set your amplifiers input sensitivity setting, quickly and accurately, with no special equipment needed. The RD500/1 features a durable, black powder-coated finish and a top-mounted, dual-color LED light strip that reports the overall status and condition. With the addition of an RBC-1 remote level control (sold separately), you can control the subwoofer output directly from the drivers seat.
