RetroSound® Quadraphonic 4-channel Amplifier

Power your whole system with the RetroSound® Quadraphonic amplifier.

The RetroSound® Quadraphonic amplifier is a plug-and-play solution for adding additional power to your classic car stereo system. The Quadraphonic is a 4-channel amplifier and connects directly to your RetroSound radio delivering 45-watts RMS to all four speakers. Pair it with a RetroSound 8" powered subwoofer for a complete audio system that's a breeze to install. The Quadraphonic amplifier offers an exceptional dynamic range and low distortion with built-in variable high-pass filters for both front and rear channels.

Listen to your favorite 60's rockabilly or 80's pop hits in your classic ride with perfect clarity and experience the music the same way you do in your daily driver. Dual gain control allows you to match the input sensitivity to the output of your RetroSound radio for the best possible audio reproduction in your classic vehicle.

The amplifier's ultra-low current draw, advanced shielding, and compact size of just 7.05” x 3” x 1.65” allows installation almost anywhere, even behind the dashboard, where most amps fail due to electrical interference!

Customer Reviews (4.6 / 5 · 5 reviews)

Ella P. ★★★★★

Installed it in my classic car’s dash and it woke up the whole system—the plug-and-play harness saved me from splicing anything, and those 45 watts per channel are plenty for my four door speakers.

Joseph E. ★★★★★

Wasn't sure 45 watts per channel would be enough, but it fills my truck cab way louder than I need. The four channels let me run front and rear speakers separately, and the plug-and-play wiring saved me a ton of time.

Carter D. ★★★★★

Dropped this in to run four speakers in my old wagon and it pushes them way louder than the head unit ever did. The plug-and-play wiring made it a 20 minute install, no cutting harnesses. Four channels at 45w RMS each is plenty for door speakers and a pair of 6x9s.
