Diamond Audio DES1000.5D 1000W RMS Diamond Elite Series 5-Channel Full-Range Class-D Amplifier

Diamond Audio DES1000.5D

The Diamond Audio DES Series 5-Channel Full Range Class D Amplifier, engineered for premium car audio performance, system efficiency, and installation flexibility. As part of the flagship Diamond Elite DES Series, this amplifier delivers powerful, dynamic sound while maintaining a compact and uniform design across the lineup.

Built with advanced Class D digital amplifier technology, the Diamond Audio 5-channel amplifier provides (90W RMS x 4+150W x 1) at 4 ohms and (150W RMS x 4+250W x 1) at 2 ohms, delivering clean, distortion-free output for both speakers and subwoofers. With bridging capability up to 300W x 2 and 500W x 1, this versatile amplifier is perfect for powering a complete system from a single chassis.

Engineered with the latest digital chipset and full PWM power supply, the DES Series amplifier ensures efficient performance with THD as low as 0.03% and a strong signal-to-noise ratio up to -96.7dBA, providing exceptional clarity across the entire frequency spectrum.

Fine-tune your system with variable high-pass and low-pass crossover controls (35Hz–350Hz), allowing precise tuning for front, rear, and subwoofer channels. The Diamond Audio DES amplifier also features balanced differential inputs for clean, noise-free signal transmission and a high damping factor for improved speaker control and tighter bass response.

Installation is simplified with multiple auto turn-on options (VOX, DC offset, and REM), ensuring compatibility with factory and aftermarket head units. Built-in short circuit, thermal, and voltage protection safeguards your system, while the compact chassis allows flexible mounting in a wide range of vehicles.
