For radios with only 2 inputs, set the Stereophonics input switch to 2 channel mode and the amplifier intelligently routes the selected inputs to all three balanced outputs. The Stereophonic is 2-ohm and 4-ohm stable and bridgeable, giving you more flexibility to build your system.\u003c\/p\u003e\n\u003cp\u003eThe Stereophonic Class D (digital) amplifier allows you to listen to your favorite classic hits at higher volumes with little to no distortion, thanks to its low current draw and exceptional dynamic range. High-pass and low-pass filters let you fine-tune your audio for the best listening experience, with gain and bass boost controls to help dial in the perfect amount of bass.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e3-channel amplifier\u003c\/li\u003e\n\u003cli\u003eFull-range Class D digital circuitry\u003c\/li\u003e\n\u003cli\u003e65-watts RMS x 2 channels full-range @ 4 ohms\u003c\/li\u003e\n\u003cli\u003e170-watts RMS x 1 channel subwoofer @ 4 ohms (229-watts RMS @ 2 ohms)\u003c\/li\u003e\n\u003cli\u003eSelectable input mode switch for 2 and 3 channel operation\u003c\/li\u003e\n\u003cli\u003eBridgeable\u003c\/li\u003e\n\u003cli\u003e2-ohm and 4-ohm stable\u003c\/li\u003e\n\u003cli\u003eBuilt-in variable low pass and high pass full-range filters\u003c\/li\u003e\n\u003cli\u003eBass boost and gain control\u003c\/li\u003e\n\u003cli\u003eAdvanced circuitry and thermal protection\u003c\/li\u003e\n\u003cli\u003eEasily connects to your RetroSound radio via RCA inputs\u003c\/li\u003e\n\u003cli\u003eWorks with any aftermarket radio with low-level RCA outputs\u003c\/li\u003e\n\u003cli\u003eDimensions: 9.4 in x 5.3 in x 1.87 in (24 cm x 13.4 cm x 4.75 cm)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eOptional Wiring Kit\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSimplify the installation of your RetroSound® Stereophonic amplifier with this convenient wiring kit that includes everything you’ll need to get your 3-channel amplifier installed.
