Description

The Reiss RS-SD300.4D is a high-performance 4-channel Class D amplifier designed to deliver powerful output with excellent sound quality and low power consumption. With 450W RMS per channel at 2 ohms, 300W RMS at 4 ohms, and 900W x2 in bridge mode at 4 ohms, you have complete flexibility to power demanding speakers or combine channels for even more power.

The wide frequency range of 20 Hz to 20 kHz ensures that the amplifier handles everything from deep bass to crystal-clear highs with precision. With a signal-to-noise ratio of 95 dB, you get clean sound free from parasitic noise, while the low THD of 0.3% guarantees pure sound even at high volume levels.

What sets the RS-SD300.4D apart is its exceptional combination of a 95 dB SNR (among the best in its range) and a THD of only 0.3%. This dual performance ensures sound reproduction of exceptional purity and fidelity, even in the most demanding environments. The Class D architecture ensures maximum efficiency, reducing power consumption and heat dissipation.

• 4-channel Class D architecture for maximum efficiency and low consumption
• 95 dB SNR for crystal-clear sound without background noise
• 0.3% THD for faithful music reproduction
• High power per channel for demanding speakers

⚠️ 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 strongly advised to adapt the power supply (additional battery, reinforced alternator) to the amplifier's consumption to avoid any risk of damage and ensure optimal performance. ATTENTION: Any voltage drop below 12V can damage the product.
