I had to do a simple high-quality mono amplifier circuit that would work with 12volt batteries at the request of our brother. TDA2030 was a good choice.
We don’t know that mp3 / mp4 players are quite common constantly evolving with a wide range of audio outputs that can be upgraded to a complete sound system to be used as the source of the player in the simplest and cheaper than the simplest of a Chinese flash drive in the non-SD card used in models from the circuit board circuit on the circuit of the mp3 player feed With the LM317 added 1.5volt regulator.
For more information and calculations with this Regulator, I suggest you take a look here
I made my integrated work very easy to install with a few simple passive components to prepare the PCB troublesome I have prepared the PCB circuit of the single-feed application from the TDA2030 datasheet file that we will use with a 12-volt battery.
The result was quite good results in the 4-ohm loudspeaker 14watt power according to the information can be used with 12v battery, we can not get full efficiency but still enough and clean sound received a simple filter added to the input 12volt 12Volt output from a coil computer PSU power supply circuit I used to remove the coil I removed
PCB File .lay extension Sprint-Layout 5.0 you can open the program if you do not use the program for free only for monitoring and printing the Sprint-Layout-Viewer program.
