## Overview

The Pioneer GM-A3702 is a 2-channel bridge amplifier delivering up to 500W of clean, powerful sound. Featuring automatic signal detection and high-voltage input level control, it seamlessly syncs with OEM receivers, including those without RCA outputs. Its balanced isolator input circuit minimizes noise like alternator whine, ensuring premium audio clarity. Compact and durable with a sleek black/red aluminum alloy design, this amplifier is engineered for easy installation and reliable performance.

## Description

2-channel bridge amplifier Pioneer amplifiers automatically select the appropriate input signal mode, cinch or speaker mode. When the receiver is turned on, the amplifier will automatically turn on. When connected to an OEM receiver or receiver without RCA output and using the speaker level output, the amplifier automatically senses the input mode and turns on in sync with the receiver. When connected to an OEM receiver or receiver without RCA output via a speaker cable, the amplifier will be switched on at the same time as the receiver. Pioneer amplifiers automatically detect input signal and select RCA level or speaker level.

Review: Previously I had a Crunch amp and it gives the alternator whine when I press on the accelerator. Tried many ways to fix it with capacitors and better grounding but it can only be fixed by turning down gain all the way. After changing to this, it sounds really clean even with the gain being turned up by default, despite having reused all the old power and grounding cables.
Review: Très facile d'installation. J'ai un 10" 400 watts et l'amplificateur le prends très bien. Ne deviens pas trop chaude pour l'instant. Reste à voir sa longévité à long terme car je ne l'ai que depuis 24 hres. Arrivé en même pas 24 hre.

Some scumbag stole my sub woofer power amp out of my Honda Pilot. This was a great replacement and paired perfectly with my new Pioneer car stereo. Good a and fast delivery. Way cheaper than the audio shop wanted to charge me for a smaller lower powered amp. Just fit under the passenger seat with no obstructions.
