Features
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 a typical Class AB amplifiers. That makes them more versatile in terms of installation as well as performance.
Packs a Punch
The 4-channel amplifier is rated at a total of 1200 watts, with the A and B channels rated at 150 watts x 4 (RMS) at 2 ohms, or 300 watts (RMS) at 4 ohms x 2 when bridged.
Auto 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.
High-Quality Affordable Design
Pioneer designed a high-quality power supply to sustain constant power requirements.
Hi-Res Certified
An optimal printed circuit board design reduces signal interference, improves channel separation, and provides better dynamics and lower distortion.
Gold Plated Terminals
Gold plated terminals provide the ability to maintain an accurate signal with increased electrical conductivity, prevent corrosion and provide enhanced durability with excellent resistance against 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.
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 performanc.

A wired bass control remote also lets you easily control the amount of bass from the subwoofer output (SW).

The GM-DX871 is a 1-channel subwoofer amplifier that can deliver up to 800 watts RMS to your subwoofer, providing powerful bass with a strong and heavy beat. CTA-2006 compliant, this highly efficient Class D amplifier offers 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. Additionally, a wired bass control remote enables you to easily adjust the amount of bass from the subwoofer output. The GM-DX871 amplifier uses high-current, high-grade electronic components and gold-plated RCA connections to ensure maximum performance.

The link300.4mini is in a class by itself. The most obvious thing is its extremely small size, but don’t Iet that fool you. Unlike most small footprint amplifiers, the link300.4mini is bridgeable. It can easily drive a nice set of components as well as a subwoofer. The link300.4mini has Wāvtech’s best in class LOC, with built-in loading and the ability to handle up to 40V of hi-level input. Perhaps the most unique feature is the built-in summing. For factory audio systems that don’t have a full range signal, the link300.4mini can handle that internally, so no additional processor is required. The level trim adjustment allows for fine tuning the output of each pair of channels. As if all of that isn’t enough, the link300.4mini is compatible with OEM start/stop systems as well. link300.4mini Features 300 Watt 4-Channel Amplifier 50 watts x 4 @ 4 ohms 75 watts x 4 @ 2 ohms 150 watts x 2 @ 4 ohms BTL Small Footprint Only 6.4”x4.5”x1.65” Variable Hi/Low Pass Crossover (-12dB/oct) Built-In Summing w/Level Trim Adjustment Start/Stop Sytem Compatible Differential Balanced Inputs Variable Gain Adjustment w/Clip LED Auto Turn-On via DC-Offset or Audio Signal Detect Adaptive OEM Load Technology Locking Detachable Hi-Level Speaker Terminals Professional Grade Panel Mount RCA’s Compact Aluminum Chassis w/Detachable Mounting tabs link300.4mini Specifications Input Sensitivity SPK: 1-20Vrms, 2-40Vrms RCA: 0.2V-5Vrms, 0.4V-10Vrms Max Input Voltage (SPK): 40Vrms Frequency Response: 45kHz (+0/-3dB) THD+N: 80dBA (1W, 4Ω)
