Technophonic 5-Channel Amplifier + R-TW84 Shallow-Mount Subwoofer Bundle

Bring modern sound to your classic car or truck with this perfectly matched bundle. The RetroSound® Technophonic 5-Channel Class D Amplifier provides four full-range channels to power your speakers plus a dedicated subwoofer channel — making it the ideal partner for the ultra-thin R-TW84 8-inch Subwoofer.

With only 2 inches of mounting depth, the R-TW84 fits where traditional subs can’t, delivering deep, accurate bass without compromising space. When paired with the Technophonic, you get a balanced, powerful system that combines clear highs, rich mids, and tight low-end response — all designed for easy integration into vehicles with limited room.

This bundle is perfect for enthusiasts who want a complete, high-performance upgrade that preserves the original look and feel of their classic ride while enjoying the benefits of modern audio technology.
