Alpine R-A90S R-Series 6/5/3 Channel Power Amplifier with Staggered Power. Experience your music in Hi-Res with the versatile R-A90S 6-Channel Amplifier for hair-raising details that puts you in the center of the performance.
6-CHANNEL AMP WITH 5-CHANNEL POWER
The R-A90S has a unique staggered power channel layout that has double the power on the last two channels. When looking to power a dual subwoofer configuration, the R-A90S’s 5th and 6th channels can be bridged to provide up to 500-watts at 4Ω. The R-A90S is matched in power and performance for the Dual 10-inch Alpine Halo S-Series Preloaded Subwoofer Enclosures with ProLink™.
AN AMP THE GROWS WITH YOU
Thanks to the unique staggered power channel layout, the R-A90S can host different levels of power on each channel, compared to traditional, multi-channel amplifiers. This allows the R-A90S to grow with you as it can effectively function as both a 3-way active amplifier and a 5-channel amplifier by delivering the power you need to the channels where you need it the most.
