Pioneer GM Series Class-D 4-Channel Amplifier - GM-DX874

Pioneer GMDX874 GM Series Class-D 4-Channel Amplifier

Step up your car's audio game with the Pioneer GMDX874 4-channel amplifier. The mighty yet mini Pioneer GMDX874 is crafted for a versatile fit and easy installation into all kinds of vehicles, thanks to its small size—half the size of the brand's class-AB amplifiers. Car audio is a game of swappability and customization, and finding the right audio components for your car can be tough. If you've never heard of an amp like the Pioneer GMDX874, this tech is designed to take in a weak, low-voltage signal from your car's stereo, then cleans and boosts it as the signal moves to your car's speakers. If you're upgrading your car audio, an amp like this is a must-have.

Boosted Bass & Variable LPF/HPF

Pioneer knows that one thing every driver wants out of their car audio amplifier is extra bass, and it's why they've upgraded the Pioneer GMDX874 amplifier with higher bass capabilities. The wired bass control remote lets users easily adjust the levels of lows in their car to match their listening preferences perfectly. And you won't need to worry about poor audio quality from the wrong signals; the Pioneer GMDX874 is designed around a variable low-pass filter. Between variable LPF and HPF, the audio frequency is adjustable to fit your preferences and what your subwoofers need. Adjust between 40HZ and 500Hz to hear things just the way you want to.

Better Design, Optimized Circuitry

This mini-master of audio is made for more than just bass: it's crafted for truly efficient circuitry. The Pioneer GMDX874 is designed with the circuit's Protection Control System. This can detect an unsafe rise in internal temperature, and can lower the amplifier's input level to help drop the temperature. The result is smarter circuitry that tries not to fry itself, even when you're busy enjoying the best elements of your playlists.

Key Features

• 1,200 Watts Max Power
• High Quality Textured Aluminum Panel and Tough Frame
• Gold RCA Terminals
• Hi-Res Audio capable
• Bass Boost Remote Included

Features

• Big Power, Small Size
  Pioneer's new extra-efficient Class-D digital 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
• Improved Circuit Design
  To prevent circuit shutdown, Pioneer's new digital amplifier circuit "Protection Control System" senses its internal temperature and automatically moderates input level accordingly. Stable, durable circuitry lessens the risk of high input power for the unit to achieve 1 ohm connection. This design enhances the flexibility to connect multiple subwoofers to a system
• Variable-Low Pass Filter
  For extra flexibility, variable LPF and HPF make audio frequency more adjustable according to subwoofer characteristics and personal listening preferences. The GM-DX874 LPF and HPF are adjustable from 40 Hz to 500 Hz
