Warzone WZ4000-1D Gravity 4000W Max Class D Monoblock Car Sub Amplifier

Product description

Build a More Commanding Bass System

Monoblock Class D amplification for dedicated car subwoofer installations

The Warzone Gravity WZ4000-1D car amplifier delivers up to 4000W maximum power in a bass focused monoblock design. Its brushed black aluminum chassis, silver mesh side grilles, illuminated top accent, and included wired level knob create a purposeful foundation for a car sound system upgrade built around compatible subwoofers.

Put Bass Tuning Within Reach

The control end of this car audio amplifier brings key setup adjustments together for a clean, deliberate installation. Use the adjustable 40 to 180Hz low pass filter to set the upper bass cutoff, the OFF to 50Hz subsonic filter to tailor very low frequency output, and 0 to +12dB bass boost to refine impact for a compatible enclosure and subwoofer. RCA line level inputs support source integration, while the 300mV to 6V input sensitivity range helps with gain matching.

Adjust Output From the Driver Seat

The included wired bass level remote knob gives the driver a convenient way to adjust subwoofer output while seated. Its clearly marked LEVEL and MAX positions support quick changes when music, road conditions, or listening preference call for more or less bass presence. Pair this remote control with the amplifier’s filter and bass boost settings to create a more personalized car stereo amp setup for compatible audio components.

Focused Power for Subwoofer Systems

The Warzone Gravity WZ4000-1D is a single channel car amplifier created for dedicated car subwoofer systems. Its Class D amp architecture concentrates amplification into a monoblock amplifier format, making it a focused choice for aftermarket bass applications where a compatible subwoofer and enclosure are the center of the system. With up to 4000W maximum power, this bass amp brings substantial output potential to a car audio amplifier installation.

Tuning flexibility is central to the WZ4000-1D design. The adjustable 40 to 180Hz low pass filter lets installers establish the amplifier’s upper operating range to better blend bass with the rest of a compatible car sound system. An OFF to 50Hz subsonic filter offers another layer of low frequency setup control, while 0 to +12dB bass boost provides a selectable lift for listeners seeking added low end emphasis. The 8 to 180Hz frequency response at minus 3dB supports coverage from deep sub bass through upper bass.

For source integration, this car stereo amp offers 300mV to 6V input sensitivity and 22K ohm input impedance for compatible line level signals. A MOSFET power supply operates on 11 to 15V DC vehicle electrical systems. With an 80dB signal to noise ratio and total harmonic distortion below 0.1%, the amplifier is specified to support controlled, detailed bass reproduction. The wired level remote adds accessible output adjustment after installation, helping make daily bass changes simple and direct.

The brushed black aluminum chassis and silver mesh grilles give this subwoofer amplifier a bold, technical appearance that suits performance oriented vehicle interiors and trunk installations. This is a bass focused car audio amplifier for builders who want adjustable low pass filter control, bass boost options, Class D efficiency, and a single channel layout for a compatible subwoofer stage.

The Warzone Gravity Series WZ4000-1D is a monoblock Class D car amplifier designed for dedicated car subwoofer applications. Delivering up to 4000W maximum power, this single channel bass amp concentrates its output on the low end of a compatible car sound system. It is suited to aftermarket installations built around a compatible subwoofer, enclosure, and line level source, whether the goal is deeper everyday bass or a more assertive car audio amplifier upgrade.

This subwoofer amplifier provides meaningful adjustment for system tuning. Set the adjustable low pass filter from 40 to 180Hz to define the upper bass range delivered to the subwoofer system. Use the subsonic filter from OFF to 50Hz to tailor very low frequency operation for the enclosure and setup. The 0 to +12dB bass boost control gives another way to shape low end emphasis. An 8 to 180Hz frequency response at minus 3dB supports bass reproduction from deep sub bass into upper bass for more tailored integration.

The WZ4000-1D supports compatible aftermarket source signals with 300mV to 6V input sensitivity and 22K ohm input impedance. Its MOSFET power supply is specified for 11 to 15V DC vehicle electrical systems. An 80dB signal to noise ratio and total harmonic distortion below 0.1% support controlled signal performance for a detailed bass presentation. These specifications help installers match the car stereo amp to compatible line level equipment and establish a balanced gain structure.

A wired bass level remote knob is included for convenient output adjustment from the driver position. The amplifier is finished in brushed black aluminum with silver mesh grilles, combining durable looking hardware with a distinctive performance inspired style. For a car sound system upgrade centered on a dedicated bass channel, the Warzone Gravity WZ4000-1D combines maximum power capability, adjustable low frequency controls, and a focused monoblock amplifier layout. Made in Vietnam.
