Overview: JX Amplifiers

JX amplifiers apply our no-nonsense, pure performance philosophy to a high-value package.

Utilizing rugged MOSFET power supplies and beefy output transistors, JX amplifiers deliver clean, rock-solid performance and reliability at an affordable price. All JX amplifiers are equipped with flexible signal processing capabilities and fully variable crossovers for easy system setup and optimization. Monoblock models also include a port for an optional Remote Level Control (RBC-1, sold separately). Low-level RCA and hi-level inputs make integrating with OEM and aftermarket head units a snap. With quality components and affordable design, JX amplifiers will keep you smiling with great sound for many years to come. Return to JX amplifiers.
