JX Amplifiers apply our no-nonsense, pure performance philosophy to a high-value package.
When you inspect a JX amplifier, you will see that nothing is spent on gimmicks, blue lights or chrome. Instead, you'll see specified 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 significantly more reliability than the wimpy devices commonly found in many competing products. All of these components add up to solid bass definition and cleaner, louder high frequency output that gets the most out of your speaker system.
To get your system dialed in just right, we also include flexible signal processing capabilities with fully variable crossover filters, pass-through preamp outputs and a Bass EQ. The monoblock models also include a port for an optional Remote Level Control (RBC-1, sold separately).
We know you’re going to be really happy when you see how affordable JL Audio JX amplifiers are, but our real goal is to keep you smiling with great sound in your car for many years to come. That’s why we put the good stuff under the hood.
