Automatic Signal Sensing and Turn-On
Pioneer amplifiers automatically select the proper input signal mode, either RCA or speaker level. When the receiver is turned on, the amplifier automatically turns on. When connected to an OEM receiver or a receiver without RCA output and utilizing speaker level output, the amp automatically senses the input mode and powers up in sync with the receiver.
When connected to an OEM receiver or a receiver without RCA output using speaker wire, the amplifier is turned on at the same time as the receiver. Pioneer's amplifiers automatically detect the input signal and select RCA level or speaker level.
Loud and Clear
Why put an amplifier in your car? Pioneer's GM-A4704 4-channel amplifier will greatly improve the sound quality in your vehicle, so you'll find yourself looking forward to your time on the road. This punchy Pioneer will power your front and rear speakers with 40 watts RMS each, which is actually a large jump over the power supplied by a typical car radio. You'll hear much more of the little details in your music, especially when you turn your system up to overcome road noise.
Tone Controls
The front channels sport variable high-and low-pass filters so you can better adjust the sound for critical front soundstaging or a finely-tuned bass. Switchable high- and low-pass filters on the rear channels help take the rumble away from full-range speakers or the sizzle away from a sub. Speaker-level inputs allow you to add the GM-A4704 to a factory system. If your vehicle needs a sonic upgrade, this amp's performance features and reasonable price make it a great choice.

Installed with fhs501bt head unit and 4 4way pioneer speakers. Easy install. Really woke up the sound. Now I want a sub. Definitely recommend this amp!

Installed this amp yesterday in my 2017 Chevy Sonic to power (2) Pioneer TS-A6970F 6x9’s and the sound is amazing, couldn’t be happier. Crutchfield recommends 10 gauge power wire but I went with 8 gauge and it seemed to work great, ran amp hard for a couple hours yesterday with no issues. Great amp for the money I would definitely recommend.
