The Power Acoustik RE1-4500D is a Class D monoblock car amplifier rated at 1125 watts RMS into 4 ohms and 2250 watts RMS into 2 ohms, with a 4500-watt peak figure. It runs full range, has variable 12dB low-pass and subsonic crossovers, a 12dB bass boost, and accepts 200mV to 6V high- or low-level inputs. A dash-mounted remote gain knob and 4-gauge power terminals round it out. It suits budget subwoofer builds that want big claimed power from a small Class D chassis; at this level, brands like Kicker and Rockford Fosgate publish conservative, verified ratings, while this one leans on peak numbers.
