    • This is an in-house product. For troubleshooting or support queries, please reach out to us directly on Facebook or by email at
    • We recommend using this product with our premium 1W speaker
    • Please keep in mind that the GBA always puts out a low-level hissing or high-pitch noise due to the GBA's hardware. An amplifier will make this noise louder. If you’re sensitive to these kinds of noises, an amplifier is not for you
    • Please note that this product may not perform as expected when batteries are low
    • This product is intended for use in the Game Boy Advance, but it can be installed in the Game Boy Color since you can safely supply 5 V, despite what's written on the board. Follow the instructions in our GBA guide but solder the 3.3 V wire to pin 7 (top), ground to pin 4 (bottom), DT to pin 5 of the headphone jack, and SP-In to the speaker in on the PCB. Please note that we currently do not offer additional instructions or support for how to install this product in any console other than the Game Boy Advance. Please note, while we have received feedback from our customers regarding successful installation of the audio amplifier in the Game Boy Color, this installation will be performed at your own risk.

    Audio Amplifier replacement

    Haven't had the chance to install it yet, but Retro Modding has been incredible in helping me replace a wrong piece of my order. You guys are fantastic and will be the first I go to for my next project.

    its pumps

    This audio amp does exactly what you've read it does. So does the upgraded speaker available (make sure to add on a 3d printed color ring for xtra swag). So does the audio cleaner flex PCB available. I've got all 3 in my Game Boy Advance right now and I am happily grooving out at half volume.

    Awesome little amp

    This is a great amp for the GBA, the difficulty was a little hard especially trying to solder the wire to the headphone jack. I just went around the board and soldered it to the leg instead. The only downfall I see from this is that when I put a game to sleep it has a buzzing noise. But overall it's nice and loud compared to the oem speaker
