You know you're holding a serious piece of sound equipment when you feel the heft of a JX amp. JL Audio designed these amplifiers 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 metres on the outside of these amps, but you will find oversized output transistors and rugged MOSFET power supplies inside. The sleek, high-mass aluminum heatsink keeps things cool enough to virtually eliminate thermal shut-downs.

The JX250/1 mono amp puts out up to 250 watts RMS to your sub, so you'll experience plenty of full bass in your music. Use the variable low-pass filter and bass boost to tune the amp to your subwoofer system. An optional remote level control lets you turn the sub up or down from the front seat. The amp includes speaker-level inputs, along with preamp inputs and outputs, so it's ready to work in virtually any system.
