GM-A3702

2-Channel Bridgeable Amplifier (500W)

Configure your perfect audio setup.

A compact, flexible amplifier that works as a stereo two-channel unit or bridges into a single channel for more power.

The Pioneer GM-A3702 delivers 190W RMS across two channels. Bridge it and you get up to 500W from a single channel — useful if you want to drive a subwoofer without buying a separate mono amp. It handles both 2 Ohm and 4 Ohm speakers, so it fits most existing setups without rewiring. Gain adjustment goes up to 6.5V, giving you accurate matching to your head unit. The one-body heat sink manages heat efficiently, and distortion is kept very low for clean output at higher volumes.

Key Features

  • 190W RMS output across 2 channels
  • Bridgeable for up to 500W total output
  • Compatible with 2 Ohm and 4 Ohm speakers
  • Gain adjustment up to 6.5V
  • One-body heat sink design for efficient cooling
  • Very low distortion for cleaner audio

About the Pioneer GM-A3702

From our tech experts at CEN

A 2-channel amplifier, rated at 190w RMS. Enough channels for a front and rear stage, or a front stage with the rest bridged onto a sub.

Who it suits

Drivers who have upgraded their speakers and found the head unit cannot drive them properly.

Our tech experts advise

Power figures mean little until the amplifier is matched to the speakers and the gains are set with a meter rather than by ear. It needs a fused feed from the battery on the correct cable gauge. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.

Frequently Asked Questions

Q: How do I choose the right amplifier for my speakers or subwoofer?

A: Match the amplifier's RMS output per channel to the RMS handling of your speakers or subwoofer at the same impedance. The Specification tab lists the power figures. If in doubt, contact CEN with your setup and we will recommend a match.

Q: What wiring do I need to install this amplifier?

A: You will need an amplifier wiring kit sized to the amplifier's power draw, typically including power and earth cable, a fuse, RCA leads and a remote wire. CEN stocks complete wiring kits, and the amplifier's fuse rating is the guide to the cable gauge required.

Q: What class of amplifier is this and does it matter?

A: Class D amplifiers are compact and efficient, ideal for subwoofers and modern installs. Class AB designs are traditionally favoured for outright sound quality on mid and high frequencies. The class is listed in the Specification tab where provided.

Q: Will an amplifier work with my factory head unit?

A: Yes, in most cases. If your head unit has no RCA outputs you will need a line output converter to feed the amplifier a clean signal. CEN stocks line output converters and can advise the right one for your vehicle.

Q: Can CEN install this amplifier?

A: Yes. CEN offers professional amplifier installation from our Nottingham premises, including secure mounting, wiring and setup. Contact us to book.
