Alpine HDA-V90 Status Series Hi-Res 5-Channel Full Range Amplifier
Build a powerful, high-resolution vehicle audio system with the Alpine HDA-V90 Status Series 5-channel amplifier. Designed to power a complete system from a single chassis, the HDA-V90 combines four full-range speaker channels with a dedicated subwoofer channel for a clean, efficient system configuration.
The HDA-V90 delivers 75 watts RMS x 4 plus 300 watts RMS x 1 at 4 ohms, or 100 watts RMS x 4 plus 500 watts RMS x 1 at 2 ohms. The first four channels can also be bridged to produce 200 watts RMS x 2 at 4 ohms, giving you additional flexibility when configuring your system.
Designed for high-resolution audio systems, the HDA-V90 provides an ultra-wide 8Hz–60kHz frequency response. Alpine's high-efficiency digital circuit design and Dual Negative Feedback Control Circuit are engineered to minimize distortion while maintaining accurate signal reproduction.
Variable high-pass and low-pass crossovers allow you to properly configure the amplifier for your speakers and subwoofer. The dedicated subwoofer channel also includes a variable subsonic filter and adjustable bass EQ for additional control over low-frequency performance.
The HDA-V90 supports selectable high- and low-level inputs, along with 2-, 4-, or 6-channel input configurations. Automatic turn-on with remote sensing makes integration easier with factory and aftermarket systems, while three sets of true 4V preamp outputs allow additional amplifiers to be added as your system grows.
With its premium copper-plated chassis, one-sided terminal layout, quick-connect terminals, and top-panel controls, the HDA-V90 combines high-resolution performance with practical installation features.
