The Power Acoustik VA41800D is a four-channel Class A/B full-range car amplifier from the Vertigo series. It rates 100 watts RMS per channel at 4 ohms, 160 watts at 2 ohms, and 320 watts bridged into two channels, with an 1800-watt max rating. It has variable 12 dB high-pass and low-pass crossovers, 12 dB bass boost, high- and low-level inputs, and a hybrid aluminum heatsink. It suits budget builds running four speakers or two speakers plus a bridged sub, but its Class A/B design runs hotter and less efficiently than Class D rivals, and its max rating is a peak figure, not RMS.

Owner feedback on the Vertigo series is limited and mixed. Buyers who run it within its RMS ratings report solid output for the money, while others question the inflated max-power claim and note heat buildup.
The Power Acoustik VA41800D is a 4-channel, Class A/B full-range car amplifier from the Vertigo Series. It is rated at 1800 watts max. It delivers 4 x 100 watts RMS at 4 ohms and 4 x 160 watts RMS at 2 ohms. Bridged, it delivers 2 x 320 watts RMS at 4 ohms.
The amplifier has a hybrid aluminum alloy heatsink and a MOSFET power supply with audiophile grade IRTM transistors. The PCB is military grade SMT. Direct short, thermal and overload circuits protect the amplifier.
It accepts hi/low level inputs, including a low level RCA input of 200mV to 6V. Variable 12dB high pass and low pass crossovers are built in. A 12dB bass boost increases low octave harmonics. Connections are made through barrier strip wire terminals.
