3D Printed Casing for Bluetooth Amplifier TDA7492P

I've earned an old amplifier with speakers that a friend was throwing away and since the amplifier was not working, I decided to recycle the speakers with an wireless bluetooth set.

Step 1: Check Your Speakers and Choose Your Audio Amp Board

there is a variety of audio amp boards you can get.

i got this one but you can pick an appropriated one for your project.

in my next build i'll try this one for 3W speakers:

it's up to you or the needs of your project. just check some reviews first, the one i got didn't had an AUX line in...

Step 2: Choose and Check a Power Supply

check your amp board schematics for the power supply info.

in my case its 8-25V DC. and i have a box full of old ones.

always check the Voltage to see if it's working well

Step 3: Design a Fancy Enclosure for Your New Amp. System!

Measure the PCB and design 3D file in the CAD software of your choice.

ex.: solid works, fusion 360, sketch up, rhino, blender, etc....

Step 4: 3D Print or Build Your Own Case

if you use the same board as I did, feel free to download and print my design.
