Is your system showing it's full potential? Amplifiers send a cleaner current to your car speakers. In layman's terms, this means that your stereo gets cleaner sound and frequency, ensuring a higher sound quality overall.

CEA2006 Specifications:
  • 60 Watts x 4, at 4 ohms <= 1% THD+N
  • 150 Watts x 2, at 4 ohms BRIDGE <= 1% THD+N
  • 80 dBA Signal-to-Noise Ratio (Reference: 1 Watt Output)

The 4-channel GM-6300F delivers a whopping 600 watts max (60 watts x 4 or 150 watts x 2 at 4 ohms; 75 watts x 4 at 2 ohms) plenty of juice to power your high-quality speakers. It's also got built-in 4-channel crossovers. Speaker level inputs for easy connection to an OEM headunit. Oversized power terminals. And a wide input level of 400mV to 6.5V.

Inspired By Excellence

Pioneer is constantly finding ways to make amplifier technology better. With added design features like the H-Shaped chassis, inherited from our top of the line PRS amplifiers, our improved GM-Series prove how you can add cutting edge technology and more power to your system without breaking the bank. Like all Pioneer products, these amps are fully tested to ensure that each is designed and built for performance.

Higher Power

Having more power isn't just about LOUD. It's also about CLEAN, getting the most out of your speakers and your music. Constant noise makes it hard for the music to be heard clearly. But with 600 watts max. power, you'll get to hear all the words and all the notes.

Superior Ground Parts

High levels of electric current can easily create noise within an amplifier - especially ground noise. To avoid this, Pioneer made careful consideration when designing and selecting components for use within the amplifier. Only the best, most efficient parts were selected after repeated testing to provide a superior noise-free listening experience.

The Best Just Got Better

For getting the music just the way you like it, crossovers are tough to beat. You can route the low frequency signals (80Hz or lower, -12dB/octave) to the speakers that handle them best, and filter out the higher-frequency signals. This optimizes your system's efficiency and delivers the best possible sound quality.

Exclusive H-Shaped Chassis

The H-shaped bottom chassis utilizes Pioneer's expertise and exclusive technologies to eliminate resonant vibrations. Directly inspired from Pioneer's high-end PRS-A900 amplifier, the H-shaped bottom chassis ensures that the music is reproduced as intended - loud and clear.

Efficient Sub-Heatsink

MOSFETs generate high power, and in many cases, high heat as well. When designing the amplifier chassis Pioneer utilized a main heatsink and a sub-heatsink to dissipate heat from the MOSFETs. These efficient heatsink structures ensure that the MOSFETs and the amplifier keep their optimal cool.

Gain Control

What is power without control? To accommodate the varying range of signal levels coming from today's factory and aftermarket radios, all of Pioneer's GM-series amplifiers feature adjustable gain controls. This means that no matter what kind of radio is connected to this amplifier, the appropriate gain control adjustment can be made to ensure loud, clear, distortion-free music. And even if the gain control level is set improperly, Pioneer's Gain Control Caution feature will automatically reduce the amplifier's output until the headunit volume is decreased to acceptable levels. This added layer of protection helps to prevent damage from occurring to the amplifier and the speakers connected to it due to improper gain control adjustments.

Bringing The System Together

What, you DON'T own a Pioneer headunit? Well, we won't hold it against you. In fact we'll even help you build onto your system. The GM-6400F's speaker level inputs allow you to connect your OEM unit (or any unit that doesn't have the typical RCA-type inputs) without having to buy add-on adapters. SO, the install goes faster, you save money, and you've got a Pioneer amp in your vehicle.
