Description

The Reiss RS-SD450.4D is an extremely powerful 4-channel Class D amplifier, designed to drive advanced speaker systems with high output and low distortion. With an impressive power of 675W RMS per channel at 2 ohms, 450W RMS at 4 ohms, and the ability to bridge up to 1350W x2 at 4 ohms, you get a power central capable of handling both mid-bass and full-range speakers with ease.

The amplifier covers a frequency range of 20 Hz to 20 kHz, offering full reproduction from deep bass to clear highs. A total harmonic distortion (THD) of just 0.3% ensures clean, distortion-free sound even at high sound pressure levels, while a signal-to-noise ratio of 90 dB delivers clear sound free of parasitic noise.

What particularly distinguishes the RS-SD450.4D is its exceptional THD of 0.3%, the lowest in the entire Reiss range. This ultra-low distortion guarantees musical reproduction of exceptional fidelity, even when the amplifier is pushed to its limits. It is the ideal amplifier for audiophiles who want no compromise between power and sound quality.

• 4-channel Class D architecture for maximum efficiency and low heat generation
• THD of 0.3% - the lowest in the Reiss range
• High power per channel for high-performance speakers
• Ultra-powerful bridged mode (1350W x2) for demanding subwoofers
• Ideal for high-end complete systems and SQ competition

⚠️ IMPORTANT - INSTALLATION: It is IMPERATIVE to connect this amplifier at the impedance recommended by the manufacturer and to use the recommended wire gauge. For amplifiers over 2000W RMS, the vehicle's original battery is no longer sufficient. It is highly recommended to adapt the electrical power supply (additional battery, reinforced alternator) to the amplifier's consumption to avoid any risk of damage and to guarantee optimal performance. WARNING: Any voltage drop below 12V can damage the product.
