It provides a single amplified channel with stable operation at 1, 2, or 4 ohms. This makes it suitable for builders who need a dedicated bass amplifier for a custom vehicle audio upgrade.\u003c\/p\u003e\u003cp\u003eRated output is 1800 watts RMS at 1 ohm, 1150 watts RMS at 2 ohms, and 650 watts RMS at 4 ohms. Its 4000-watt maximum-power rating is paired with a compact amplifier chassis. The selectable impedance capability gives installers flexibility when matching compatible subwoofer wiring configurations.\u003c\/p\u003e\u003cp\u003eThe WZ4000-1D is intended for systems where low-frequency output is the priority. A variable low-pass crossover helps focus the amplifier's output on bass frequencies, while the adjustable bass boost allows low-end tuning. A supplied bass knob provides a convenient way to adjust bass level from the listening position.\u003c\/p\u003e\u003cp\u003eGravity uses a MOSFET pulse-width-modulated power supply in this amplifier. The Class D design and heat-dissipation approach are intended to support efficient operation in a vehicle electrical system. A variable subsonic filter is also provided to help tailor the low-frequency operating range for the connected subwoofer system.\u003c\/p\u003e\u003cp\u003eHigh- and low-level inputs support integration with a variety of source-unit signal types. The amplifier includes protection for high voltage, low voltage, over-current, and high-temperature conditions. Its compact 11.3-inch-long footprint can be useful when planning a dedicated subwoofer amplifier installation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMonoblock Class D Design:\u003c\/strong\u003e Delivers dedicated single-channel power for a subwoofer system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1-Ohm Stable Output:\u003c\/strong\u003e Supports compatible 1-, 2-, and 4-ohm subwoofer loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1800W RMS at 1 Ohm:\u003c\/strong\u003e Provides its highest listed continuous output at 1 ohm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMOSFET PWM Power Supply:\u003c\/strong\u003e Supports efficient power conversion for vehicle audio use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Bass Controls:\u003c\/strong\u003e Includes adjustable low-pass, bass boost, and subsonic settings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour-Way Protection:\u003c\/strong\u003e Monitors voltage, current, and temperature-related operating conditions.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe WZ4000-1D uses a compact chassis measuring 11.3 by 8.3 by 2.5 inches.
