SKU: RD1000/1 Categories: , , Brand:


The RD1000/1 from JL Audio is designed specifically with high-power subwoofers in mind, providing a whopping 1000 W of power and loaded with features, this amp provides everything you need to have a next-level bass experience.

Plenty of Power.

The JL Audio can deliver an impressive 1000 W of output into 2 ohms (14.4V, 1% THD) or 600W at 4 ohms giving you rich, thundering bass that can be heard over the noise of the road. And thanks to  JL Audio’s proprietary NexD™ Technology, all of that power is delivered in a way that is highly-efficient and minimizes distortion, giving you the best listening experience without taxing your vehicle’s electrical system too much.

Superior Sound Control

JL has taken the hassle out of fine tuning your audio experience by placing all of the audio controls at the very top of the amplifier underneath a convenient protective cover. This amp also features a 12 dB / octave low-pass filter, with continuous variable frequency selection fro 50-500 Hz, as well as a variable bass boost EQ. Automatic turn-on capacity (via signal sensing or DC-offset  sending) is standard, along with a set of preamp outputs so signals can be passed to another amp with ease.

Quality and Design

JL builds it’s products out of durable materials, and the RD15000/1 is absolutely no exception.  This amp features a black powder-coated finish, accented by an LED light strip that runs across the body and doubles as a status/condition indicator.
