JL Audio RD900/5 5-channel car amplifier — 70 watts RMS x 4 at 4 ohms + 500 watts RMS x 1 at 2 ohms

Power your entire system

JL Audio’s RD900/5 5-channel amplifier will send 70 watts RMS to each your car’s front and rear speakers, while delivering up to 500 watts RMS to a sub. Or, for louder applications, you could switch your RD900/5 to 3-channel mode and run a pair of high performance speakers with 200 watts each and still send 500 watts to a sub. An optional wired remote lets you adjust the sub’s volume from your front seat.

Low current demand, low distortion, and easy integration

The RD900/5 plays your music with true fidelity and impressive impact, without straining your car’s electrical system, thanks to JL Audio’s proprietary NexD™ amplifier technology. “Differential-balanced” inputs keep the incoming signals clear of outside noise, and allow you to connect this amp to just about any radio. The speaker-level inputs feature two auto turn-on modes so you can readily incorporate this amp into a factory system — no need for RCA connections or a remote turn-on lead for this setup. 

LED clip lights and other cool features

High-pass filters, low-pass filters, and a bass boost help you dial in the perfect tone for your speakers and subwoofer. Onboard LED clip indicators let you set the amp gain quickly and accurately with the use of a test tone. A removable cover hides the amp’s controls, resulting in a handsome appearance and a tamper-resistant installation. Cool blue LED accent lighting adds some charm to this amp’s rugged good looks.
