Gravity Audio Warzone E1500.1D Class D Monoblock Car Amplifier

The WARZONE E-1500-1D is a compact mono Class D car amplifier designed for powering a subwoofer system. It provides a single amplified channel and is stable with a 1-ohm speaker load. Its rated output is 1500W RMS at 1 ohm, with lower-output ratings available for 2-ohm and 4-ohm system designs.

This amplifier is suited to listeners building or upgrading a dedicated bass section in a vehicle. A mono amplifier concentrates its output on a subwoofer channel, making it appropriate for systems that use separate amplification for full-range speakers. Select the final subwoofer wiring configuration carefully so the total load remains within the amplifier's supported range.

The E-1500-1D uses a Class D amplifier platform and a MOSFET pulse-width-modulated power supply. Its listed construction includes a double-sided FR-4 circuit board, high-quality SMD components, and a full-range MOSFET circuit design. These elements support an efficient, compact amplifier layout for vehicle installations.

Onboard adjustment provisions include adjustable low-pass and high-pass filters, plus adjustable bass-boost frequency and level controls. A wired remote bass knob is included for convenient level adjustment from the driver's seat. These controls allow the amplifier to be matched more closely to the subwoofer, enclosure, source unit, and the rest of the audio system.

The amplifier includes protection provisions for high voltage, low voltage, overcurrent, and high temperature. It is intended for 12V DC vehicle electrical systems and should be installed with appropriately sized power, ground, fuse, speaker, and signal wiring. It can serve as the subwoofer amplifier in a new build or as a replacement for a lower-powered mono amplifier.

Key Features

• 1500W RMS at 1 Ohm: Provides the highest stated continuous output when connected to a properly wired 1-ohm load.
• Mono Class D Design: Uses a single-channel, efficient amplifier format intended for subwoofer duty.
• 1-Ohm Stability: Supports subwoofer wiring arrangements with a final 1-ohm load.
• Remote Bass Knob: Includes a wired remote level control for accessible bass adjustment.
• Adjustable Filters: Offers adjustable low-pass and high-pass filtering for system tuning.
• Four-Way Protection: Monitors high voltage, low voltage, overcurrent, and high-temperature conditions.

Design & Installation

The E-1500-1D uses a compact chassis with a double-sided FR-4 PCB, SMD components, and MOSFET-based circuitry. Its Class D architecture and listed heat-dissipation design are intended to support efficient operation in a vehicle audio environment. The compact format can be useful where amplifier mounting space is limited.

Install the amplifier securely on a solid surface with airflow around the chassis, and use a direct fused power connection, a short solid ground connection, and correctly sized wiring for the system. Match the connected subwoofer or subwoofer array to a final 1-, 2-, or 4-ohm load; do not wire below the stated 1-ohm stable load. Set gain, crossover, and bass-boost controls conservatively during setup, and use the included remote bass knob for routine level changes.
