Diamond Audio DMD1100.6D 6-Channel DMD Series Full Range Class-D Digital Car Amplifier

Diamond Audio DMD1100.6D

The Diamond Audio DMD Series 6-Channel Full Range Class D Digital Amplifier, engineered for power, flexibility, and value in modern car audio installations. Designed to drive full-range speakers and subwoofers from a single amplifier, this 6-channel car amplifier delivers dynamic performance with efficient power output.

Built with advanced Class D digital amplifier technology, the Diamond Audio 6-channel amplifier produces 125W x 4 + 250W x 2 at 2 ohms and 80W x 4 + 125W x 2 at 4 ohms, offering versatile power for multi-speaker setups. With bridging capabilities up to 500W x 1 at 4 ohms and dedicated subwoofer channel options delivering 700W x 1 at 2 ohms, this amplifier is ideal for powering a complete audio system with clarity and authority.

Engineered with 4-layer FR4 PCB construction and advanced SMD circuitry, the DMD Series amplifier ensures reliable performance, efficient heat dissipation, and long-term durability. Balanced differential inputs provide clean, noise-free signal transfer, making it perfect for both factory and aftermarket integrations.

Fine-tune your sound with variable high-pass and low-pass crossover controls (50Hz–500Hz), allowing precise tuning for speakers and subwoofers. Whether you’re building a fully active system or a traditional front/rear/sub setup, this full-range Class D amplifier delivers balanced, distortion-free sound across the frequency spectrum.

Installation is simple with selectable 2-channel or 6-channel input modes and REM, VOX, and DC turn-on options, ensuring seamless compatibility with any head unit. Built-in short circuit, thermal, and voltage protection safeguards your system, while the compact chassis allows flexible mounting options.
