The Pioneer GM-DX971 is a single-channel Class D amplifier built to drive one subwoofer hard. It is rated at 500 W RMS into 4 ohms, 800 W into 2 ohms and 1200 W into 1 ohm, so it suits subs that want big power in a compact chassis. A 40–240 Hz low-pass filter and 10–240 Hz rated response keep it focused on bass, and the 75 dB signal-to-noise figure is ordinary rather than exceptional for the class. It is not bridgeable and not rated for boats, so it is a car-audio part. Against pricier mono amps it gives up some flexibility and refinement, but it delivers strong 1-ohm output for the outlay.

Owner feedback on this amp centers on strong output for the money and easy setup, with most complaints about heat and the lack of tuning extras rather than sound quality.
