About the JL Audio JD400/4 4-channel Class D full-range amplifier

From the manufacturer

JL Audio JD400/4 Compact and Versatile: Fits nearly anywhere: 9.50 x 7.50 x 2.10 in. (242 x 190 x 53 mm) Ultra-flexible outputs, capable of multiple configurations:4-Ch. Satellite Amp: power front and rear speakers with 75W x 43-Ch. System Amp: power front speakers with 75W x 2 and a sub with up to 200W2-Ch. High-Power Satellite Amp: power 2pr. of speakers with 200W x 22-Ch. High-Power Subwoofer Amp: drive two subwoofers with 200W x 2 NexD™ Switching Amplifier Technology: Our advanced high-speed switching technology delivers outstanding fidelity with very low noise and distortion. Exceptional efficiency results in reduced current draw and heat, permitting reliable high power output within a very small chassis. Full-bandwidth operation in all channels. (20 Hz - 20 kHz bandwidth) Complete Signal Processing Sections: 12dB/octave high or low-pass filters for each channel pair, defeatable, with fully variable frequency selection from 50-500 Hz. Preamp outputs (buffered, pass-through type, from CH. 1&2) Dual-Range, Differential-Balanced Inputs and Automatic Turn-On Capabilities: NO NOISE! Outstanding noise rejection prevents alternator whine and other noises. Accepts line-level or speaker level signals up to 8V RMS, including those from factory systems, without a line-output converter (LOC): just splice wires to a pair of RCA ends or RCA cables. Selectable Input Mode switch permits one pair of inputs to feed both pairs of output channels. Automatic turn-on option via Signal-Sensing or DC-Offset sensing Integrated LED Clipping Indicators for Easy Setup: Simplifies input-sensitivity setting by providing accurate visual feedback of output clipping level.1) Disconnect one speaker output wire2) Play full-scale (0 dBfs) sine-wave through audio system, with head unit at 3/4 volume and tone controls set flat.3) Adjust input sensitivity until light turns on, then back off slightly.

Match the numbers to your setup

The specs above are the fastest way to confirm a part is right before checkout — a size or power rating just outside your factory setup usually means an adapter or a different SKU, not a return later. If you are not sure which spec matters for your vehicle, the fit tool at the top of the page narrows the catalog to parts already confirmed for your year, make, and model.
