Jensen JA5B
Five-channel MOSFET amp for speakers plus sub with RGB app lighting
$249.99
Overview
The Jensen JA5B is a 5-channel Class D MOSFET amplifier that can drive four speakers and a subwoofer from one chassis. Bluetooth app control manages RGB illumination and setup, with high-level and RCA inputs for factory or aftermarket sources. Variable gain and crossover controls help balance midrange and bass without a separate DSP in many installs. Install with adequate power wire, ground, and fuse. Match speaker and sub impedance to the amp’s ratings before finalizing gain.
