This flex amp for the Game Boy Advance enhances the audio and also addresses issues with other flex amps that are too loud and don't have adjustability. 


  • Please purchase your speaker separately (2W)
  • Variable volume pot labelled "TRIM". This will adjust the peak volume of the amp. Set this during install with a small flat head screwdriver.
  • Preinstalled additional capacitators to reduce speaker hum.
  • If using an original speaker, there will be slight distortion at the maximum volume and the tabs on the back of the speaker may need to be trimmed
  • Compatibility with Dehum/Dehiss kits still to be tested. 


  • 1x GBA Audio Flex amp


  • Remove the old speaker and trim off the old solder connections so they are flat with a pair of side cutters.
  • Pre-tin the GBA motherboard (see photo showing locations).
  • Solder on the flex amp at the four locations (see photo). I suggest to use a small amount of liquid flux to help neaten to joints and allow the solder to flow.
  • Solder on the speaker.
  • Using a small 2mm flat blade screwdriver (iFix part "2"), set the volume pot to the required peak level.


  • This amp has a 'silence' mod installed. Which means that, when the volume wheel is closer to the off position, the volume will become completely silent. This helps to reduce the humming/hissing noises that can be heard when an amp is installed. However, please expect a less gradual increase of volume from off to receiving sound, it will start off at a higher-level volume than a quiet one.

Danielle Patterson
Flex Amp

Sounds awesome!! Thank you so much!!

Good amp love the adjustability

Pretty easy install everything lined up. Adjusted the potentiometer on the flex amp to get the max volume I wanted. Has full range adjustability. You can actually set it too high to where it will start to "clip". Very clean install.
P.S. if you hear crackling, your speaker is probably hitting the grill of the case which can be fixed by lowering the amplification. I spaced my speaker out a bit with thin enameled wire and trimmed the speaker feet to get more volume, more of a speaker issue. Mine is the 2W speaker.

Great mod

Great modification. Pretty easy to do. I can hear my games in noisy environments.

Great upgrade

Excellent upgrade. I bought it knowing that I would it figure it out. Volume is excellent. For those looking to adjust the potentiometer, by trial and error I found out that turning clockwise lowers de voltage (bringing the max volume a little lower but also allowing to lower volumes to be played when bringing the volume wheel below 50%). I kept mine that it mutes around 25% but still brings a nice loud volume. There was no noise from the speaker, even when bringing the potentiometer higher. I also upgraded to the 2W speaker as needed.

Excellent product

It’s my first time doing soldering in over 3 years ever since the pandemic I’ve been doing mods for classic consoles. I’m still getting the hang of it. Thank you!
