Dear All,
I have built up a small project of stereo amplifier using TDA 2822M. I am using regulated 5v power supply. And speaker has 4 Ω 10w configuration. I give input to circuit through mobile. Now, when I run circuit at low volumes it runs clean and fantastic. But as I increase volume through 47k POT from mid to high, my speakers starts distorting . And I cant get clear sound. Also bass is not that much good in speaker (Though it has rubber cone ring , just like sub woofer) . When bass effect comes in music, speaker volume goes down... please provide me solution. I want to build custom good bass speaker system for my laptop.Even I used some large 4ohm 10w speakers. But they are also showing same distortion at high volume.
Please find circuit & speakers used by me in attachment.
