Power Acoustik VA4-1800D Vertigo Series 1800W Max Class A/B Full-Range 4 Channel Car Amplifier

Power Acoustik VA4-1800D

The Power Acoustik VA4‑1800D delivers clean, consistent multi-channel power without unnecessary complexity. Built as part of the Vertigo Series, this 4-channel Class A/B full-range amplifier strikes a balance between traditional analog warmth and modern signal control, giving you the flexibility to drive door speakers, tweeters, or even bridge channels to a compact subwoofer.

At 1800 watts peak and 640 watts total RMS, the VA4‑1800D supports system upgrades where sound quality and installation space both matter. Whether integrating with a factory head unit or feeding signal from an aftermarket source, this amp adapts—thanks to high-level signal sensing input and low-level RCA compatibility.
