Audio Zerone ZE2000.1 4000W Monoblock Class D MOSFET Subwoofer Amplifier – 1Ω Stable, 1-4Ω, Low Pass

Powerful, efficient bass for your car system

The Audio Zerone ZE2000.1 is built for bass enthusiasts who want clean, impactful sub bass without adding bulk. It delivers up to 4000 Watts MAX x 1 at 1 Ohm and 1000 Watts RMS x 1 at 1 Ohm, giving you serious headroom to drive a demanding subwoofer while keeping a compact footprint.

Key design choices help you tailor your setup to your vehicle and listening preferences. The Class D topology minimizes energy waste, which reduces heat and allows for a lighter, smaller package. A MOSFET power supply provides steady voltage delivery, supporting a confident bass response as music peaks rise. With a 1 Ohm stable configuration, the ZE2000.1 can continuously power heavier loads, making it a solid match for subs that crave extra current.

Safety, reliability, and installation flexibility

Protective features safeguard both the amplifier and the vehicle’s electrical system. Thermal protection, overload protection, and short-circuit protection help maintain safe operation during long listening sessions or dynamic track changes.

Practical specifications and layout matter when upgrading a car audio system. The ZE2000.1 measures 11 inches by 6.9 inches by 2 inches and weighs 6.6 pounds, offering a compact footprint suitable for under-seat, trunk, or hidden installs. The built-in low-pass crossover lets you focus bass frequencies where they belong, reducing midrange bleed for crisper, more controlled deep bass.

In real-world use, you may notice tighter bass response, less heat buildup at higher volumes, and a more streamlined install process thanks to the evolved, sturdy chassis. These are possibilities that complement a well-chosen sub and enclosure, rather than guarantees, and will depend on your vehicle and setup choices.
