This circuit can actually deliver up to 70W at 4 ohms at 10% THD at 14.4V power supply which is very suitable for car audio applications. Make 4 of this amplifier and you will have a powerful 280W audio system for your car which will be very loud.
I have designed a quick PCB for this amplifier and you can download it for free for those who want to build it. I have no plans to build this amplifier for now but I may build it when I find some time. For now you can use my design for your own project and let me know how it performs.
Take note that this design is just a quick one. Meaning I have not yet check on the sizes of the capacitors. I have included the eagle PCB design just in case you want to modify this design. If you have build it, please let us know through our facebook page. You can also contact us through facebook if you have some questions regarding this design.
