Automotive Mono Amplifiers

Alpine HD-Series Mono Class-D Full-Range Hi-Resolution Automotive-Grade Amplifier, 800-Watts @ 2-Ohms or 500-Watts @ 4-Ohms Using expertise gleaned from over five decades of crafting premium car audio products and trickle-down engineering and design from the Ultra Hi-Res AlpineF#1Status system technologies, the Alpine Status System features exceptional tooling and rich build quality for the best possible sound reproduction. Each component was hand-picked from the highest-quality materials for the highest in-class audio performance, that when used as a complete system, can achieve 192kHz/24Bit playback. Powering a Hi-Res sound system without contributing noise during playback requires efficiency and precision and the HDA-M80 was intentionally designed to provide impressive power output to the system while ensuring the purest audio performance. The amplifier’s wide dynamic range capability provides impressive output in a compact chassis that fits most vehicle applications. The HDA-M80 features a high-efficiency digital circuit design that ensures ultra- low distortion levels for precise sound reproduction and superb sound quality. Intentional designs, like a copper-plated chassis and black circuit board, bring the signal-to-noise ratio up to 83dB and minimize noise and distortion during playback for complete music fidelity that’s true to the original source. Featuring technology unique to Alpine, the amplifier features Alpine’s dual negative feedback control circuit to improve linearity for the most accurate sound amplification. This technology also stabilizes the amplifier output while driving the subwoofers for ultimate reliability. The HDA- M80 features Alpine’s quick- connect power and speaker connectors for quick and safe installation. The one- sided terminal layout and top-panel sound controls give the user quick access to controls on the amplifier. The Alpine Status System is sold separately and can be used to build a custom sound system. Three sets of true 4V preamp outputs are included to add additional amplifiers if more power is needed. For best results, install the complete Alpine Status system together as a full system to achieve the highest in-class audio performance only second to the Ultra High-Resolution AlpineF#1System.

R2-Series Mono Class-D Full-Range Hi-Resolution Automotive-Grade Amplifier, 750-Watts x 1-Channel @ 2-Ohm or 500-Watts x 1-Channel @ 4-Ohm Elevate your audio with the Alpine R2-A75M Mono Amplifier - delivering powerful 750W performance in a sleek, compact design. Built with Alpine's cutting-edge Class D Amplifier Circuit, this next-generation R-Series amp offers exceptional sound quality and efficiency, making it the perfect addition to any car audio system. The R2-A75M features a reduced footprint that’s 15% smaller than the previous model (R-A75M), making it easier than ever to install in most vehicle applications while still getting the same powerhouse performance. The R2-A75M features intentional design choices that prioritize convenience and simplicity. All speaker connections are consolidated on one side of the device for easy access, while the amplifier controls have been relocated to the top under a removable plate, allowing for quick adjustments to gain and crossover controls. The amplifier's chassis also includes integrated mounting "feet" to streamline the installation process. Specifications Dimensions: 11.1” W x 2.17” H x 6.5” D Weight: 7 lbs, 10 oz Power Rating: 14.4V, ≤ 1% THD +N Power Output: 500W RMS x 1 @ 4Ω, 750W RMS x 1 @ 2Ω S/N Ratio: >75dB Frequency Response: 10Hz – 400Hz Damping Factor: >250 Alpine R2-A75M Manual
