Product Description

JL AUDIO JX250\1D Mono Subwoofer Amplifier – #99402

JL AUDIO JX250\1D Mono Subwoofer Amplifier will power your subwoofer with up to 250 watts RMS, so you can experience powerful bass in your music. A variable low-pass filter and bass boost help you tune your sub to sound its best in your system. An optional remote level control lets you turn the sub up or down from the front seat.

You know you’re holding a serious piece of sound equipment when you feel the heft of this tiny JX amp. JL Audio built it with sturdy, high-grade parts that ensure excellent heat management, provide high current flow, and deliver stable performance in almost any situation. You won’t find blinking lights or meters on the outside of these amps, but you will find oversized output transistors and rugged MOSFET power supplies inside. The high-mass aluminum heatsink keeps things cool enough to virtually eliminate thermal shut-downs.

Monoblock Amplifier

JL AUDIO JX250\1D Mono Subwoofer Amplifier will power your subwoofer with up to 250 watts RMS, so you can experience powerful bass in your music. that has been optimized for low-frequency (10-150 Hz) amplification of connected subwoofers.

Class D Amplifier Circuit

The JX250/1D employs an advanced Class D switching design that allows it to produce 160 watts of clean subwoofer power while drawing significantly less current from your electrical system and generating less heat than a conventional Class A/B or Class B design.

MOSFET Switching Power Supply

The JL Audio JX series monoblock amplifier employs a rugged MOSFET power supply for outstanding reliability and operational stability.

High-Mass Heat Sink

A heavy extruded aluminum heat sink is designed to keep the JX250/1D in a comfortable thermal range during demanding operation. This high-mass, extruded heat sink removes heat from the amplifier circuitry, extending high-power operation. This improves reliability and reduces the frequency of thermally related shut-down event.

Protection Circuitry

The JX250/1D’s protection circuitry automatically shuts the amplifier down if thermal limits are exceeded, or a short-circuit is detected in the speaker wiring.
