## Long description

The Pioneer GM-A3702 is a compact 2-channel car audio amplifier delivering up to 500 W peak output in a Class A/B design.

It integrates automatic input signal sensing and turn-on functionality, so the amplifier detects whether the source uses RCA or speaker-level inputs and powers up in sync with the receiver. The compact footprint and efficient power delivery provide a balance between performance and installation flexibility.
Suitable for
Upgrading a factory car audio system to improved amplification
Driving a pair of component or coaxial speakers in medium-power setups
Installations where compact amplifier size is required

How to use
Mount the amplifier in a ventilated location using the provided mounting points and ensure secure wiring to the vehicle chassis for grounding. Connect the receiver to the amplifier using RCA cables when RCA outputs are available; if the source lacks RCA outputs, connect speaker-level inputs using the speaker wires. Power the unit by connecting the main 12 V power and remote turn-on lead to the vehicle battery and receiver respectively. Adjust gain and crossover settings on the amplifier to match speaker sensitivity and the desired frequency response before listening at normal volume levels.
Usage recommendations
Use correct wire gauges for power, ground, and speaker connections, and verify secure, corrosion-free battery and chassis connections. When integrating with an OEM receiver, allow the amplifier’s automatic signal sensing to select the proper input mode; if noise or turn-on chirps occur, check grounding points and route power cables separately from signal cables.
