This unique 3-channel amplifier has two 65 watt RMS full-range front channels for mids and highs – plus a mono channel with up to 229 watts (2 ohms) for a subwoofer – allowing a complete audio system to be built using a single Stereophonic amplifier. Low-level RCA inputs allow Stereophonic to work with any aftermarket radio with RCA outputs. Stereophonic is bridgeable and 4 ohm and 2 ohm stable. Stereophonic offers exceptional dynamic range for the best possible sound reproduction from your RetroSound® audio system. The full-range channels have a high-pass crossover for use with full-range speakers. The mono channel has a low-pass crossover to fine tune the bass frequencies for use with a subwoofer. A selectable input mode allows switching between 2 and 3 channel operation.Stereophonic also features low current draw and Class D Digital circuitry. With exceptional dynamic range and low distortion, you'll get the best possible sound from your audio system.
Retro Manufacturing is the leading producer of audio components for the classic vehicle market. RetroSound was born from the lack of high-quality aftermarket audio offerings in the restoration marketplace. The Retrosound radio was purposefully designed to fit seamlessly into a classic application and offer modern technology with superior sound quality. RetroSound’s patented radio has become the top choice for customers seeking everyday enjoyment from their restoration project.
For over a decade, RetroSound has been providing customers with a product that is unlike anything on the market today. The product line has grown to include full audio offerings such as speakers, amplifiers, kick panels, antennas, sound dampening and more. RetroSound has also continued to improve upon their award winning radios by offering OEM licensing and industry leading technology such as Apple integration, SiriusXM compatibility, DAB+ accessibility and more.
Proudly based in Henderson, Nevada, Retro Manufacturing has been a part of the SEMA organization for the past 9 years and proactively supports the automotive restoration community and classic car enthusiasts around the globe.
