Mono Amplifier for Subwoofer Systems

The Pioneer GM-DX971 is a Class D mono amplifier built for high-performance subwoofer installations. It delivers 1200W RMS at 1 ohm, 800W at 2 ohms and 500W at 4 ohms with 1% THD. The unit weighs 6.8 lbs and includes a wired bass boost remote for convenient level adjustment from the driver seat. Gold-plated RCA terminals and a variable low-pass filter complete the feature set.

1200W RMS at 1 Ohm Decides Compatibility

The single specification that determines whether this amplifier suits your build is the 1200W RMS rating at a 1 ohm load. Your subwoofer must be wired to present a 1 ohm nominal impedance and be rated to handle approximately 1200W continuous power. If the subwoofer impedance is higher or its power handling is significantly lower, this amplifier will not operate at its rated output or may risk damaging the driver.

Handles High-Output Subwoofers Up to 1200W RMS

This amplifier comfortably drives subwoofers rated for up to 1200W RMS when wired to a 1 ohm load, with headroom provided by the 2400W max power rating. The variable low-pass filter adjustable from 40Hz to 240Hz at -12dB/oct and frequency response down to 10Hz allow precise tuning for deep bass reproduction. It runs out of clean power beyond the 1200W RMS rating at 1 ohm, and bridging is not supported for additional output.

Questions about this item

How much continuous power does the 1200W RMS at 1 ohm figure actually give my subwoofer?

The amplifier delivers 1200W RMS into a 1 ohm load, 800W RMS at 2 ohms and 500W RMS at 4 ohms, all measured at 1% THD.

What signal connection does the single RCA input use and does it limit the frequency range?

Gold-plated RCA terminals feed a variable low-pass filter adjustable from 40Hz to 240Hz at -12dB per octave, with overall response from 10Hz to 240Hz.

What mounting space and wiring does the chassis need to fit in my vehicle?

The unit weighs 6.8 lbs, uses block-style terminals for power and speaker cables, requires a negative ground and is protected by three 40A fuses.
