RD500/1 Amplifier Overview FOH Image RD
Sleek and powerful, RD amplifiers deliver outstanding amplifier performance and versatility at an unprecedented value.

Sleek aesthetics paired with a host of useful features poise RD amplifiers as a hard-to-beat value in car audio amplifiers. Founded on the same NexD™ Class D switching technology used in XD and MX amplfiers, RD amplfiers deliver a lot of power despite their compact chasis. In addition to the standard amplifier featureset, we've added two features you're sure to love. 1) We made gain-setting a breeze with LED clipping indicators and 2) we included stereo output channels that include input type switches. A simple switch, which makes using Y-adaptors when bridging a thing of the past.  Learn more about RD amplifiers.

JL Audio MX AmplifiersMX Amplfiers

Compact, powerful and versatile, MX amplifiers are built to deliver amazing sound from the smallest of spaces, plus they're water-resistant.

Employing JL Audio's highly-efficient NexD™ Class D technology, MX amplifiers generate lots of high-fidelity sound, while being kind to small charging systems. Housed in a cast aluminum chassis, MX amps are ultra-compact and water-resistant, making them perfect for installations in boats and small watercraft. Onboard filters and signal processing allow easy set-up and system flexibility. The optional M-RBC-1 (sold separately) allows subwoofer level control (MX300/1 or MX500/1) remotely from the captain's chair. Learn more about MX amplifiers.
