This 5-channel car audio amplifier is designed to power front speakers, rear speakers, and a subwoofer from a single chassis, delivering dynamic, full-range sound with exceptional clarity.
Built with advanced Class D amplifier technology, the Diamond Audio HX1200.5D amplifier maximizes power output while minimizing heat and electrical strain. It delivers 100W x 4 + 480W x 1 at 4 ohms and 150W x 4 + 800W x 1 at 2 ohms, making it ideal for complete car audio system upgrades and custom installations. The dedicated subwoofer channel provides deep, controlled bass, while the full-range channels ensure crisp highs and detailed mids.
Engineered with audiophile-grade high-tolerance components, the HX1200.5D HEX Series amplifier features a 4-layer PCB board with balanced differential inputs, ensuring clean, noise-free signal transmission. Premium SNAP capacitors and advanced circuitry deliver accurate sound reproduction and long-term reliability.
For advanced tuning, the Diamond Audio HX1200.5D Class D amplifier includes variable high-pass crossovers (40Hz–400Hz) for channels 1–4, a low-pass crossover (30Hz–300Hz) for the subwoofer channel, and a subsonic filter (10Hz–55Hz). These controls allow precise system optimization for balanced sound staging and powerful bass response.
The amplifier features an anodized extruded aluminum heat sink for superior thermal performance, while the compact yet powerful design allows easy installation in cars, trucks, and SUVs. Additional features such as output clip indicators, top-mounted controls, and an included bass remote control make setup simple and precise.
