.

Reiss RS-W460.4 is a flexible and powerful 4-channel Class AB amplifier designed to deliver high sound quality and stable output to your entire system. It combines musical warmth with raw strength and is perfect for those who want to power both speakers and smaller subwoofers with precision and balance. Its analog character provides a rich, natural sound – with control over every detail.

Powerful and versatile performance

The RS-W460.4 delivers 60 W RMS per channel @ 4 Ohm and up to 85 W per channel @ 2 Ohm, providing plenty of power even for demanding setups. When bridged, it produces 120 W RMS x2 @ 4 Ohm – ideal for driving midbass drivers or a compact subwoofer. The high damping factor ensures tight bass response and clean separation across the frequency spectrum, while low distortion (<0.3%) preserves musicality even at high volumes.

Fine-tuned sound control

With built-in high-pass and low-pass filters, you can easily 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, making the RS-W460.4 suitable for front stages, rear channels or subwoofer duty. A Bass Boost function (0–12 dB) allows you to add extra depth and impact whenever the music calls for it.

Stable construction and compact form

With an operating voltage of 9–16 V and an input sensitivity of 0.2–6 V, the RS-W460.4 works perfectly with factory head units as well as external DSP systems. Two 30A fuses provide protection and ensure reliable operation even under heavy load. Thanks to its compact dimensions of 260 × 182 × 49 mm, installation is easy even in tight spaces – perfect for discreet yet powerful setups.

Reiss RS-W460.4 is the amplifier for those seeking clean power, stable control and classic analog sound quality – built to perform at its best every time you press play.
