About The Product
The GM-A3702 2-channel amplifier will greatly improve the sound quality in your vehicle. This amplifier powers your pair of speakers with 60 watts RMS each, allowing you to hear more of the finer details in your music, especially when you turn up the volume to overcome road noise. With this amplifier, you can combine the channels to drive a subwoofer with a total power of 190 watts RMS. Additionally, speaker-level inputs allow you to add this amplifier to a factory-installed audio source that does not have pre-amplified outputs.
High-Quality Affordable Design
To prevent poor bass performance in demanding situations, such as heavy bass content or dynamic range music, Pioneer designed a high-quality power supply to sustain constant power requirements. This design enhances audio performance by providing a better signal-to-noise ratio, improved audio dynamics, sustained bass when needed, and, most importantly, a more enjoyable ride in your car!
Automatic Signal Sensing and Turn-On
When used with an audio source such as an OEM source or a receiver without RCA output, the amplifier will activate as soon as an audio source is detected through the speaker level outputs. When using a pre-amplified source (RCA), this Pioneer amplifier will use the signal (+12Vdc) from the “Remote” input for activation.
Built-in Filter
The amplifier features a switchable 80 Hz low-pass filter (LPF) to precisely adjust the audio bandwidth and optimize the acoustic performance of your subwoofer.
