Hey! everyone My name is Steve.

Today I’m Gonna show how I Build this Class D Audio Amplifier Using TDA3116D2 Board it Can deliver up to 100 watts each channel This amplifier uses 2 TDA3116D2 Chip each can do 100 watts @2 Ohms

Amplifier Type is Class D

Sound Quality is really impressive

For Test, I’m gonna use only 3” 30-watt speakers

You can easily drive 6”-8” inch drivers

Step 5: Marking & Drilling

I Used a Philips Head Screw Driver to Open the Encloser
And Then I placed the SMPS and Amplifier one by one on top of the bottom part of the Encloser and used a Center Punch to Punch 4 Holes for SMPS and 2 holes for Amplifier
And then I used a 3mm Drill Bit to Drill the Punches

Note - Please see the images for better understanding

Step 6: Drilling Back Panel

For AC Input Socket I've traced the square on the back panel
And then used 4mm drill it to cover all the traces "See the Image"
And then used a Dremel tool to trim
And then used a bigger file to trim more
and then used a small file for finishing

For Audio Output I used a Female Speakon Socket So, I used a 3mm Drill Bit to drill the corresponding holes and then I used a Step Drill bit to enlarge the holes

Note - Please see the images for better understanding

Step 7: Drilling Front Panel

For Volume Controle I used a 10K Dual Gang Potentiometer So, I used a 3mm Drill Bit to drill the corresponding holes and then I used a Step Drill bit to enlarge the holes
For led and 3.5mm audio input socket I've used 4mm drill bit
