This powerful 5-channel amplifier has four 65 watt RMS full-range channels for mids and highs – plus a mono channel with up to 330 watts (2 ohms) for a subwoofer – allowing a complete audio system to be built using a single Technophonic amplifier. Low-level RCA inputs allow Technophonic to work with any aftermarket radio with RCA outputs. Technophonic comes with a wired remote gain control module that allows you to adjust the bass output on the fly.

Technophonic 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 4 and 5 channel operation.

Technophonic 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.
