Power up your music
JL Audio's JX Series amplifiers were very popular with our customers, garnishing rave reviews citing their tremendous performance and value. We think their latest JD Series amps will follow in their footsteps, offering superior power and serious features for your dollar. The JD400/4 four-channel amplifier will send 75 watts RMS to each of your front and rear speakers, guaranteeing you'll hear and feel your music clearly over road and engine noise. JL Audio designed this amp to power high-performance speakers like their premium C3 and C5 Series components. If you're just looking to fill your ride with bass, you can configure this amp for two-channel operation in order to power a pair of subwoofers with up to 200 watts RMS each.
Convenient features
Variable high- and low-pass filters allow you to tune the amplifier to match your particular speaker or subwoofer system. The amp includes speaker-level inputs with signal-sensing amp turn-on, along with preamp inputs and outputs, so it's ready to work in virtually any system. Differential-balanced inputs plus JL Audio's NexD™ amp technology keep the signal sounding pure and noise-free at all times.
