1000W 4Channel Bridgeable Amplifier - Pioneer GMA6704

Untitled Document

Inspired By Excellence

Pioneer is constantly finding ways to make amplifier technology better. Our new and 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 road noise makes it hard for the music to be heard clearly. But with 480 watts max. power, you'll get to hear all the words and all the notes.

Variable LPF/HPF

Variable LPF (low-pass filter) and HPF (high-pass filter) allow for adjustable frequency between 40 Hz to 500 Hz and greater car audio system flexibility according to subwoofer characteristics and personal listening preferences. The GM-A6704 has a variable LPF/HPF on Ch. B and fixed LPF/HPF on Ch. A.

High Capacity Switching Power Supply

To suppress power supply loss, GM-Series amplifiers incorporate a large toroidal transformer and are driven using a high-speed switching MOSFET. This stabilization of power supply maintains stable playback of all types of music.

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-A6704'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.

I have a 2018 Transit custom running original head unit, going to upgrade door speakers to 180 watt ones and possibly an active bass speaker under seat so what would be the best amp to use please

Answer:
hi,

you could use the amplifier to run the speakers as it would be perfect for that, the subwoofer will have its own amplifier so you will have two spare channels for adding some extra speakers in the rear if you wish too, if not then you could just go for a 2 channel model
