Monoblock Class D Subwoofer Amplifier, 500 W x 1 @ 2 Ω / 300 W x 1 @ 4 Ω - 14.4V
This rugged and reliable Class D monoblock uses a robust MOSFET power supply design that delivers rock-solid bass performance at a very affordable price.
Targeted specifically for subwoofer applications, the JX500/1D includes a low-pass filter with continuously variable cutoff frequency selection from 50-200 Hz. It also features a variable bass boost at 45 Hz. with up to 12 dB of boost and an optional remote boost control. Dedicated hi-level inputs are included, in addition to conventional low-level RCA inputs, making it easy to integrate with a variety of OEM and aftermarket head units.

Class D Circuitry
Subwoofer-optimized, Class D amplifier circuit delivers high efficiency without sacrificing low-frequency fidelity.
The design of our Class D subwoofer amplifier circuits places a high emphasis on damping of the driven load and low-frequency control. Exceptional efficiency is also achieved, which allows the amplifier to be physically compact and also draws far less current from a vehicle’s electrical system during high-power operation.
