Three JX Monoblock Subwoofer Amplifiers are specifically optimized for superior sub-bass performance and are available to suit a wide range of subwoofer system applications, from 250W all the way to a full 1000W of power. By contrast, when you inspect a JL Audio JX amplifier, you will see that nothing is spent on gimmicks, blue lights or chrome. Instead, we apply our 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.
