About The Product
The GM-DX971 is a 1-channel subwoofer amplifier that can deliver up to 1,200 watts RMS to your subwoofer, producing powerful bass with a strong and heavy beat. CTA-2006 compliant, this highly efficient Class D technology provides impressive, high-quality power in a compact chassis. The speaker-level inputs allow you to install this amp in a factory system without RCA connections. The built-in low-pass filter lets you optimize the sound for your vehicle’s interior. A wired bass control remote also lets you easily control the amount of bass from the subwoofer output. The GM-DX971 amplifier uses high-current, high-grade electronic components and gold-plated RCA connections to ensure maximum performance.
Turn Up the Bass
This amplifier features a wired bass control remote for optimal bass level adjustment according to your listening preferences and the characteristics of the music.
Big Power-Small Size
Pioneer’s extra-efficient Class-D amplifiers mark a dramatic improvement in power output capability, yet are 50% smaller than the current GM-Series Class-AB amplifiers. That makes them more versatile in terms of installation as well as performance.
Packs a Punch
This mono amplifier is rated at a total of 2400 watts (max power) with high-current circuitry that provides all the power you need, delivering 500 watts RMS at 4 ohms, 800 watts RMS at 2 ohms, and up to 1200 watts RMS at 1 ohm. Stable, durable circuitry reduces the risk of high input power, allowing the unit to achieve a 1 Ω connection. This design enhances the flexibility to connect multiple subwoofers to the system.
Automatic Signal Sensing and Turn-On
When used with an audio source such as an OEM source or a receiver without RCA output, the amplifier will activate as soon as an audio source is detected through the speaker level outputs. When using a pre-amplified source (RCA), this Pioneer amplifier will use the signal (+12Vdc) from the “Remote” input for activation.
High-Quality Affordable Design
To prevent poor bass performance in demanding situations, such as heavy bass content or dynamic range music, Pioneer designed a high-quality power supply to sustain constant power requirements. This design enhances audio performance by providing a better signal-to-noise ratio, improved audio dynamics, sustained bass when needed, and, most importantly, a more enjoyable ride in your car!
Gold Plated Terminals
These terminals maintain an accurate signal with increased electrical conductivity, prevent corrosion, and offer enhanced durability with excellent resistance to wear.
Pioneer’s TVC (Total Vibration Control)
Pioneer’s TVC (Total Vibration Control) concept used in this amplifier not only increases the rigidity of the unit but also counteracts vibrations that affect sound quality at various points. The fixing points of the main board are optimized to completely suppress external vibrations and small vibrations caused by circuit parts. It adopts a heat sink structure that optimizes the position of large components, mounting screws, heat dissipation, and mechanical vibration suppression.
Protection Control System (PCS)
Pioneer’s PCS continuously monitors the input voltage, current consumption, and operating temperature to automatically adjust the amplifier’s output, ensuring operational stability during long listening sessions or when installed in high-temperature environments.
Independent Variable Filters
The amplifier features a variable high-pass filter (HPF) and a variable low-pass filter (LPF) ranging from 40 Hz to 500 Hz to precisely adjust the audio bandwidth and optimize the acoustic performance of your speakers and/or subwoofer. Additionally, to give you even more control, these filters are completely independent for channel “A,” channel “B,” and the subwoofer output (SW).
