DIY 5.1 Amplifier

Hello everyone,

I found an affordable speakers set for a 5.1 sound system and decided to build the amplifier myself. 🛠️
With three stereo amplifiers that I found for less than €20, you can cover all 6 channels needed for a 5.1 sound system.

I also 3D printed a housing for it and installed everything inside. It works great, just had to use Ground Loop Isolators on all audio inputs to avoid any humming in the speakers.

If you want more details about it, I made a YouTube video: https://www.youtube.com/watch?v=0Mgx2k_e6QM
