DIY TPA3116D2 100W amplifier with Bluetooth, MP3 and FM for home and car audio

So here’s a little cheap amplifier project that you can build for your home or car audio which only cost you around 600 pesos. 


Bill of Materials

  • TPA3116D2 amplifier module – Php 201 – shopee link
  • Bluetooth/FM/MP3 module – Php 178 – shopee link
  • Enclosure from DEECO – Php 145
  • Others(wires,switches) – Php 50

Total is around 574 pesos only!

Note that power supply is not yet included. I am using it with my hybrid solar power which has an output of 12V which good enough for watching TV and some soft music. Power supply module will cost around 500 pesos, be sure to buy a 24V power supply instead of 12V to have the highest output power possible. At 12V, it can only deliver about half of its power capability. You can use a boost converter to increase the voltage from 12V to 26V to be able to get the maximum power output of this amplifier from a 12V power supply. Boost converter like this one on shopee.

I built it mainly for my home audio but this can also be used for car audio.
