The Hifonics A1500.1D is a Class D monoblock car amplifier built for driving a subwoofer, rated up to 1500 watts. It uses Ultra-Fi MOSFET output devices and a cast aluminum heat sink for thermal headroom, plus an Accu-Cross crossover, subsonic filter and variable phase control for tuning. High-level inputs with DC offset auto turn-on let it work with a factory head unit, and the included HFR-31 wired bass remote adjusts output from the cabin. It suits bass-focused builds that want tuning features without stepping up to a larger multi-amp system.
