System Configuration Flexibility of 4ch 3ch or 2ch with 400 watts of power
RX2 400.4 is a powerful 4ch 400W, class A/B amplifier delivering massive power to support your system’s needs. Configure as a 4ch for an active components setup or as a front/rear stage amplifier. How about for a full system? Setup as 3ch mode you can run your front stage and a subwoofer. Configure in 2ch mode for 200 watts x2 on whatever you choose. Anyway you configure it, you will be rewarded with efficient sound and musical quality while wrapped in a sleek, low profile chassis designed for versatility.
RX2 series amplifiers are the reference for style and value in any installation. Built with the legendary Phoenix Gold reliability, they feature heavy duty heatsinks, robust unregulated power supplies, and oversized direct input power and speaker terminals. They also sound sweet thanks to the audiophile-grade output transistors. We made upgrading your stock system easy by allowing high level inputs, so you can keep that hard to replace radio, and still upgrade the sound. RX2-series amplifiers are ready to impress with their effortless ability to provide power and clarity while keeping the chassis at a convenient size for any installation. The devil is in the details, so it just made sense that we allow the PG name plate to be removed and turned to match the orientation you might need for your install because we know you're going to want show off your system and make all your friends jealous.
