Rockville RD1500.1 1550W RMS 6000W Peak 1 Ohm Mono Class D Car Amplifier with Bass Remote, 150A Fuse, RCA Output for Subwoofers

The Rockville RD1500.1 is a mono Class D car amplifier designed to power subwoofers in vehicle audio systems while maintaining a compact footprint. It delivers dyno-certified output of 1550 watts RMS at 1 ohm, 1014 watts RMS at 2 ohms, and 620 watts RMS at 4 ohms, with a 6000 watt peak rating at 1 ohm. The chassis measures 14.35 x 4.92 x 1.81 inches.

A high-speed MOSFET power supply and Class D design support efficient bass amplification, while adjustable controls help tailor low-frequency response. Bass boost adjusts from 0 to 12dB at 45Hz, the low pass filter ranges from 45Hz to 200Hz, and the subsonic filter adjusts from 10Hz to 50Hz to match the amplifier to the connected subwoofer system.

The RD1500.1 accepts input signals from 0.2V to 6.0V and includes Tiffany-style RCA terminals for secure signal connections. An RCA preamp line output with 8-volt preamp circuitry supports routing to additional amplifiers, while 4 gauge power and ground terminals and 8 gauge speaker terminals accommodate high-current wiring.

An included metal bass remote provides convenient subwoofer level adjustment from the listening position and features a clipping indicator for system monitoring. The amplifier also includes an external fuse holder with a 150A fuse, mounting screws, owner's manual, and warranty card for installation support.

Full IC-controlled protection circuitry and power, protect, and clip LED indicators help monitor amplifier operation. The RD1500.1 has a frequency response of 10Hz to 200Hz, a damping factor greater than 150 at 100Hz, and minimum THD below 0.5 percent at rated power, supporting controlled low-frequency performance in compatible car audio systems.
