J2: Technologies
All motor:

When you see a moderately priced amplifier loaded with chrome and lights, you know that the money to pay for the bling came from somewhere, and that ‘somewhere’ is under the hood.

By contrast, when you inspect a JL Audio J2 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.

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 even include a wired Remote Level Control (at no extra charge).


 
 
We know you’re going to be really happy when you see how affordable 
JL Audio J2 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.

Three J2 Monoblock Subwoofer Amplifiers are available (250W, 500W and 1000W), plus two full-range J2 models (2 x 180W and 4 x 80W).
 
 
 
J2 CrossoverActive Crossover Features
Fully variable 12dB/octave filters controls offer excellent tuning flexibility.

J2 Preamp OutputsPreamp Outputs
Pass-through pre-amp outputs permit interconnection of multiple amplifiers.

J2 Bass ControlBass Control Features
Fully variable bass boost circuits are included on all models. Monoblock models also feature a wired Remote Level Controller (included).


J2 Heat SinkHigh-Mass Heatsink
A heavy extruded aluminum heat sink is designed to keep each J2 amplifier in a comfortable thermal range during demanding operation. This improves reliability and reduces the frequency of thermally related shut-down events.

J2 Class DClass D Amplifier Circuit
The J2-1000.1 employs an advanced Class D switching design that allows it to produce 1 kilowatt of clean subwoofer power while drawing significantly less current from your electrical system and generating less heat than a conventional Class A/B or Class B design.


J2Rugged MOSFET Switching Power Supplies
All J2 amplifiers employ rugged MOSFET devices in their power supplies for outstanding reliability and operational stability.
