Reiss RS-W480.4 – 4-Channel Class AB Amplifier 80W x4 @ 4 Ohm with Power, Control and Musical Precision

Reiss RS-W480.4 is a high-performance 4-channel Class AB amplifier that combines powerful output with a warm and natural sound character. It is designed to provide maximum control across the entire frequency range and works equally well for speaker systems and smaller subwoofers. The RS-W480.4 is the perfect upgrade for anyone who wants dynamic, detailed sound with an analog feel and modern performance.

Powerful performance and flexibility

With 80 W RMS per channel @ 4 Ohm and up to 110 W RMS @ 2 Ohm, the RS-W480.4 delivers enough power to drive even more demanding speakers with ease. When bridged, it provides 220 W RMS x2 @ 4 Ohm, making it ideal for powering a pair of strong midbass drivers or a compact subwoofer. The wide frequency range of 10–20,000 Hz ensures natural reproduction and clear separation between bass, midrange and highs.

Fine-tuned control

The RS-W480.4 is equipped with both high-pass and low-pass filters, making it easy to tailor the sound to your system. The high-pass filter is adjustable between 100–1,000 Hz, and the low-pass filter between 40–400 Hz, offering great flexibility for different installations. With the Bass Boost function (0–12 dB), you can add extra depth and punch whenever you want to truly feel the music.

Reliable construction and installation

The RS-W480.4 features a stable operating voltage of 9–16 V and an input sensitivity of 0.2–6 V, making it compatible with both factory and aftermarket head units. Two 40A fuses protect against overload and ensure safe operation even under high demand. Clean signal reproduction with a >90 dB signal-to-noise ratio and <0.3% THD preserves clarity at all volume levels.

Compact power package

Despite its strong output, the RS-W480.4 comes in a compact design measuring only 278 × 182 × 49 mm, making installation easy even in tight spaces. This is an amplifier that combines power, efficiency and classic sound character in a sleek, durable chassis.

Reiss RS-W480.4 is the choice for those seeking pure strength, detailed sound reproduction and stable control – every time you turn up the volume..
