Alpine R A90S R Series 6CH Amplifier

Experience Hi-Res Music with the R-A90S

The R-A90S 6-channel R-Series amplifier is one of the most versatile Class-D 6-channel amplifiers on the market, featuring a unique staggered power channel layout that has double the power on the last two channels. It also includes built-in high-pass and low-pass filters for flexible system configuration. The “R” line of speakers and subwoofers have a heritage of sound quality you can hear from a block away. These newly added R-Series amplifiers are tuned to emphasize the characteristics of the R-Series speakers and subwoofers, delivering the legendary R-Series experience.

Staggered Power Design

With double the power on the last two channels, the R-A90’s 5th and 6th channels can be bridged to provide up to 500 Watts RMS @ 4 Ohms to your subwoofer system. The unique staggered power channel layout allows you to set the amp to deliver 4x 75 Watts + 2x 150 Watts to run 2 separate subs, or configure it 4x 75 Watts + 1x 500 Watts to run one very powerful subwoofer.

The Amp That Grows With You

Thanks to the staggered power channel layout, the R-A90S can host different levels of power on each channel compared to traditional multi-channel amplifiers. It can effectively function as both a 3-way active amplifier and a 5-channel amplifier, delivering power where you need it most.
