JL Audio RD500/1 1000W Peak (500W RMS) Class-D Monoblock 2-Ohm Stable Amplifier

Power your bass

JL Audio's RD500/1 mono amplifier will power your subwoofer with up to 500 watts RMS, so you'll hear and feel the bass clearly over the whistle of the wind and rumble of the road. An optional wired remote lets you adjust the sub's volume from your front seat.

Low current demand, low distortion, and integrates well

The RD500/1 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 light and other cool features

A low-pass filter and bass boost help you dial in the perfect tone for your sub and enclosure. An onboard LED clip indicator lets 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.
