The Vibe POWERBOX65.4-8MDSP-V3 is a compact 4-channel micro Class D amplifier with an integrated digital signal processor designed to upgrade factory or aftermarket car audio systems. Its small footprint allows discreet installation in tight spaces while delivering four channels of power for door or rear speakers.

The amplifier includes a full DSP suite controllable via a smartphone app with gain control, crossover configuration, time alignment and a 31-band parametric EQ. Inputs include optical, high-level and Bluetooth to enable wireless streaming and integration with a wide range of source units.

An integrated mixer combines input signals for distribution to all channels and a remote output and auto turn-on feature simplify system integration. The unit is intended for OEM and aftermarket installations where a compact, feature-rich 4-channel DSP amp is required.
