Is your system showing it's full potential? Pioneer is constantly finding ways to make amplifier technology better. With added design features like the H-Shaped chassis, inherited from their top of the line PRS amplifiers, their improved GM-Series prove how you can add cutting edge technology and more power to your system without breaking the bank. Pioneer's Gain Control Caution feature will automatically reduce the amplifier's output until the headunit volume is decreased to acceptable levels. It feels good to have Pioneer in your vehicle.

Good sound quality for this price. Nice design and features for price also. Really can take the heat too. Ran it hard in one hundred degree weather. It was ready to start melting my car before it turned off. Finally did but let it cool for a minute and it was right back to working perfect. Great budget amp to beat up.

I had this installed under the passenger seat of my 04 F250 in conjunction with the AVH 4300 DVD player and 4 Pioneer TS-D6802R speakers. The sound is awesome. I did add 2 Pioneer shallow mount subwoofers and another Pioneer amp for the back. The subs really completed my sound.

Awesome amp! Nice power. Years back i owned a pioneer AD360 amp. It had a lot of kick and the GM-6400F is the same. Just make sure that it is connected to a 4 channel car stereo otherwire you loose sound.

I've had this system in place powering 4 60 watt speakers running at 50rms each and I've never had a problem with it. It runs a little warm to the touch after a long drive with loud music, but that's to be expected. All in all I've never noticed any negatives about this amp in the last 6 months, and expect that it will continue to preform greatly.
