Cerwin Vega XED8001D 1100W Class-D Mono Amplifier

The Cerwin Vega XED8001D is a compact mono Class-D amplifier designed to add dedicated subwoofer power to a car audio system. It delivers 450 watts RMS into 4 ohms or 800 watts RMS into 2 ohms from a single channel. This makes it a practical choice for systems built around one subwoofer or a compatible two-subwoofer load.

This amplifier is intended for listeners who want stronger low-frequency output without adding a large multi-channel amplifier. Its mono configuration concentrates its output on bass reproduction, while the variable low-pass and subsonic filters help tailor the amplifier to the installed subwoofer system. A wired remote level control provides an accessible way to adjust bass level from the front of the vehicle.

Class-D topology and a full PWM power supply support efficient operation in a compact chassis. The XED8001D is rated for a 10.0 to 16.0 VDC supply range and has an idle-current specification of 0.7A. Its 2-ohm output impedance rating allows it to support properly wired 2-ohm subwoofer loads.

Input flexibility helps the amplifier work with a range of source units. It provides RCA input connections as well as a high-level input, with separate low- and high-level input sensitivity ranges. Input gain adjustment, a crossover selection switch, and Vega Bass Boost give installers useful controls for integrating the amp into an existing system.

The XED8001D fits naturally into a staged audio upgrade where a head unit and full-range speakers are already in place and dedicated bass power is needed. Its 8.7-inch length can simplify placement in installations with limited mounting room. Use it with a subwoofer configuration that presents no lower than its rated 2-ohm load.

Key Features

• 800W RMS at 2 Ohms: Supplies substantial single-channel power for a correctly matched subwoofer load.
• Class-D Topology: Provides efficient mono amplification in a compact format.
• Variable Low-Pass Filter: Adjusts the upper bass cutoff from 35Hz to 250Hz.
• Variable Subsonic Filter: Lets you set low-frequency filtering from 10Hz to 50Hz.
• High- and Low-Level Inputs: Supports RCA-equipped and speaker-level source connections.
• Wired Level Remote: Allows convenient adjustment of bass level from the cabin.

Design & Installation

The XED8001D uses a compact black chassis measuring 8.7 x 4.7 x 1.8 inches. Its layout includes power input connections, speaker output terminals, RCA input connections, high-level input, input gain adjustment, crossover controls, a remote-level connection, and a status LED. Two 35A ATC fuses are specified for the amplifier.

Mount the amplifier securely on a solid vehicle or amplifier-rack surface, leaving room for wiring and access to the adjustment controls. Match the subwoofer wiring to a 2-ohm minimum load, then set gain and filtering to suit the source unit and enclosure. The manufacturer documentation identifies 4 AWG as the maximum input wire gauge; use appropriately fused power wiring and follow the installation manual for grounding and connection guidance.
