Diamond Audio DES1000.1D 1-Channel Elite DES Series Monoblock Class D Car Amplifier

Diamond Audio DES1000.1D

The Diamond Audio DES Series 1-Channel Monoblock Class D Amplifier, engineered for high-performance car audio systems that demand maximum output, precision control, and reliability. As part of the flagship Diamond Elite DES Series, this amplifier is designed to deliver exceptional low-frequency performance with optimal power at multiple impedance levels.

Powered by advanced Class D digital amplifier technology, the Diamond Audio DES monoblock amplifier produces 800W RMS at 4 ohms and 1000W RMS at both 2 ohms and 1 ohm, making it ideal for driving high-output subwoofers with authority. Its high-efficiency design minimizes heat while maximizing power, ensuring consistent performance during extended high-volume listening sessions.

Built with the latest digital chipset and full PWM power supply, this high-power monoblock amplifier delivers clean, distortion-controlled output with THD as low as 0.07% and a signal-to-noise ratio up to -97.4dBA. The result is tight, accurate, and hard-hitting bass that enhances any music genre.

Fine-tune your subwoofer system with a variable low-pass crossover (35Hz–350Hz), allowing precise adjustment of bass frequencies. The Diamond Audio DES amplifier also features balanced differential inputs for noise-free signal transfer and a high damping factor (>250) for improved subwoofer control and tighter bass response.

Installation is seamless with multiple auto turn-on options (VOX, DC offset, and REM), ensuring compatibility with both factory and aftermarket head units. Built-in short circuit, thermal, and voltage protection ensures long-term reliability and system safety, while the compact design allows flexible mounting in a variety of vehicles.
