All of your idea is gud and try it using tpa3116 series class D types which works on 12v single supply bcoz you know to assemble the amp circuit in plain pcb... Great work bro❤️
Thanks for suggesting but TDA7294 lC only working on Dual supply. It's not suitable for Battery powered Amplifiers. This kind of Dual supply ic running only 12 volt to 24-0-24 Dual supply converter its expensive.
Yes but you need Mic 🎤 preamp module otherwise you try this circuit . www.google.com/search?tbm=isch&sxsrf=ALeKk017mMsrEtIvWk-Iuz1Cw8-0O-SyQA%3A1584464068765&source=hp&ei=xABxXpLwLJub4-EPy7Gq8AQ&q=mic+amplifier+circuit+diagram&oq=Mic+amp&gs_l=mobile-gws-wiz-img.1.1.0l5.2041.4986..5975...2.0..0.186.939.0j8......0....1.......5..35i362i39j35i39j0i3j0i131j0i13j0i13i5i30.wxYDPIRVXj8#imgrc=NEvNrF6qtF8SEM This circuit output connected on our TDA2030 IC input..
