JL Audio JX1000/1D: Monoblock Class D Subwoofer Amplifier, 1000 W

This amazingly compact amplifiers delivers a real kilowatt of power at an unbelievably great price. Using a tough-as-nails Class D circuit with a robust MOSFET power supply, the JX1000/1D is fully capable of driving the toughest subwoofer loads with very good control and excellent sound quality.

Targeted specifically for subwoofer applications, the JX1000/1D includes a variable slope 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

Summary:
Subwoofer-optimized, Class D amplifier circuit delivers high efficiency without sacrificing low-frequency fidelity.

Detailed Information:
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.
