Produce a Monstrous Bass Output
Made to produce a monstrous bass output, the Pioneer GM-DX871 is a premium mono subwoofer amplifier that can deliver a heart-pounding bass without you having to break the bank. Thanks to Pioneer's vast experience in making quality audio components, you no longer have to settle, even on a tight budget.

Pioneer's Protection Control System
With its compact chassis, installing it in your car won't be a problem. The amplifier also uses Pioneer's Protection Control System, which is made to monitor the input voltage, operating temperature, and current consumption of the amplifier, as it will adjust its performance depending on its condition, as this will also ensure a longer lifespan for the amplifier.

Class-D Technology Design
Thanks to its Class-D technology design, the Pioneer GM-DX871 can deliver an impressive power output of 300 Watts RMS at 4 ohms and 500 Watts RMS at 2 ohms. It is also a 1-ohm stable amp, so it can handle a power output of 800 Watts RMS at the said impedance.

More Defined Low-frequency Performance
It also has a frequency response of 10 up to 240 Hz, a pretty extensive low-frequency range, especially for its size. It has a variable low-pass filter from 40 to 240 Hz, giving you a more defined low-frequency performance. It also has a variable bass boost of up to 18 dB at 50 Hz if you feel that the amplifier's bass production is still lacking.
