An amplifier built for single cab classic trucks and two speaker systems, the Stereophonic 3-Channel amplifier powers your left and right speakers at 65-watts RMS per channel and sends 170-watts RMS to your subwoofer. 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.
The 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.
