Hello, I am looking to design a PCB to handle the 3.5mm output of a computer then boost that signal to run standard"" speakers (simple $6.00 per car speaker at walmart ones).
The reason I don't want to use standard computer speakers is because I like the mounting holes for the car speakers, and besides that, at $6.00 per speaker (and I really wouldn't only need one speaker), I could get away with a really inexpensive setup.
Also, this system will only need to handle midrange... the kiosk will 'talk' to people, no heavy bass or high highs.
Does anyone have any suggestions?
I have been looking at radio shack for amp chips (I am not evensure that is the right name), but I have found LM324 chip... but I am afraid (?) that it will not be powerfull enough.
The ability to have the speakers be really loud would be a plus, but not necessary.... Also, I would like the ability to regulate the volume somehow (on the pcb)
Are there any inexpensive solutions (under 15$ for speakers + pcb + parts)?
thanks
Lee
