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 nameplate to be removed and turned to match the orientation you might need for your install because we know you're going to want to show off your system and make all your friends jealous.
