JL Audio JX400/4D 4 channel 360w amplifier


When you inspect a JL Audio JX amplifier, you will see that nothing is spent on gimmicks, blue lights or chrome. Instead, JL Audio apply their no-nonsense, pure performance philosophy to specify oversized output transistors and rugged MOSFET power supplies that ensure ample current and thermal capacity. These beefy parts operate well under their limits to deliver stable performance and vastly better reliability than the wimpy devices commonly found in many competing products. It all adds up to solid bass definition and cleaner, louder high-frequency output that gets the most out of your speaker system.

The Full-range JX360/4 offers plenty of clean power to get superb performance from your component system or subwoofers.
