Prime Series mono subwoofer amplifier

The Rockford Fosgate R2-500X1 is a Prime Series mono subwoofer amplifier built for car audio systems. It delivers 500 watts RMS x 1 at 2 ohms and 250 watts RMS x 1 at 4 ohms. The Class-D design meets CTA-2006 compliant performance standards. An included remote level control allows bass adjustment from the driver seat.

Built for single-subwoofer setups

This amplifier suits drivers who want dedicated low-frequency power for one subwoofer. The variable infrasonic filter (15-50Hz) and low-pass crossover (50Hz-250Hz) with 12dB/Oct Butterworth slope shape the output precisely. Buyers needing multi-channel amplification for full-range speakers or multiple subwoofers should look at a different amplifier topology.

Integration into a car audio build

The mono block requires 8-gauge power and ground leads with a 50-amp fuse, which are not supplied. Auto remote turn-on with a defeat switch simplifies the signal connection to the head unit. The Class-D efficiency reduces current draw, leaving more electrical headroom for other vehicle systems. Wiring, fuse, and mounting hardware must be sourced separately.

Questions about this item

What gauge power and ground leads and fuse rating does the R2-500X1 require for installation?

The amplifier needs 8-gauge power and ground leads plus a 50-amp fuse, which are not included in the box.

Will the R2-500X1 turn on automatically with a factory head unit that lacks a dedicated remote wire?

Yes, the built-in auto remote turn-on detects signal on the speaker-level inputs and powers the amp without a separate remote lead.

How can I confirm the R2-500X1 is delivering its rated 500 watts RMS at 2 ohms after installation?

The amp is CTA-2006 compliant, meaning its 500 W RMS at 2 ohms rating is verified to the same industry standard used for all compliant car amplifiers.
