JL AUDIO JD400/4 JD Series 4-Channel Car Amplifier — 75 Watts RMS x 4

Product Description:

The JL Audio JD400/4 is a versatile 4-channel full-range Class-D amplifier capable of delivering 75 watts RMS x 4 at 4 ohms (100W RMS x 4 at 2 ohms) or bridging to produce 200W RMS x 2 at 4 ohms. Utilizing high-speed NexD switching technology, it provides crisp, detailed sound across all channels while operating efficiently within vehicle electrical systems. Each channel pair includes independent 12 dB/octave high-pass or low-pass crossovers (50–500 Hz), dual-range differential-balanced inputs, and individual LED clipping indicators surrounding each gain control for simple, precise level matching.

Product Features:

• 400W Total RMS Output: Delivers 75W x 4 @ 4 Ω, 100W x 4 @ 2 Ω, or 200W x 2 bridged @ 4 Ω.
• NexD Full-Range Class-D Topology: Ultra-fast switching circuitry ensures wide frequency response and low distortion across all four channels.
• Dual LED Clipping Indicators: Dedicated LED gain-setting rings for front and rear channels allow accurate gain calibration without special equipment.
• Flexible Crossover Architecture: Selectable 12 dB/octave high-pass or low-pass filters (50–500 Hz) for versatile system configurations.
• Preamp Pass-Through Outputs: Buffered RCA outputs pass audio signals directly to a secondary subwoofer or speaker amplifier.
