Its Class A\/B design supports a broad range of speaker-upgrade layouts while operating at 2- or 4-ohm loads. It is intended for listeners who need independent amplification for front and rear speakers or other four-channel system configurations.\u003c\/p\u003e\u003cp\u003eWith a published maximum output of 1000 watts, the WZ1000.4 is built to provide added power beyond a typical head unit's internal amplifier. The amplifier covers a 20 Hz to 20 kHz frequency response range for full-range audio applications. Its signal-to-noise ratio is rated above 80 dB, while total harmonic distortion is specified below 0.5%.\u003c\/p\u003e\u003cp\u003eAdjustable crossover controls help tailor the amplifier to the speakers and system role selected during installation. The variable high-pass filter adjusts from 50 Hz to 1.2 kHz, while the low-pass filter adjusts from 50 Hz to 500 Hz. A variable bass boost control provides adjustment from 0 to 12 dB.\u003c\/p\u003e\u003cp\u003eThe WZ1000.4 includes both high-level and low-level input options, allowing it to work with many factory or aftermarket source-unit setups. Low-level RCA connections can be used with a head unit that has preamp outputs, while high-level inputs offer an option for systems using speaker-level outputs. A remote bass control is included for accessible bass-level adjustment from the cabin.\u003c\/p\u003e\u003cp\u003eIts compact published dimensions of 8.8 by 8.3 by 2.5 inches can simplify placement in many vehicle installations. The amplifier can serve as the main power stage for a four-speaker upgrade or as part of a more customized system using its crossover controls. Correct impedance matching, secure power wiring, and careful gain setup are important for dependable operation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour-Channel Class A\/B Design:\u003c\/strong\u003e Provides four amplified channels for speaker-system upgrades.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2- and 4-Ohm Stability:\u003c\/strong\u003e Supports compatible speaker loads at either published impedance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1000W Maximum Power:\u003c\/strong\u003e Supplies added amplification for multi-speaker vehicle audio systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Crossovers:\u003c\/strong\u003e HPF and LPF adjustments help match amplifier output to speakers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBass Boost Control:\u003c\/strong\u003e Offers adjustable low-frequency emphasis from 0 to 12 dB.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh- and Low-Level Inputs:\u003c\/strong\u003e Accommodates speaker-level or RCA signal connections.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe WZ1000.4 uses a compact amplifier format measuring 223.5 mm long, 211 mm wide, and 64.5 mm high.
