Audio amplifier

I'm going to build a small amplifier to fit in a 1/12 scale model car to run three 1 inch 4ohm speakers. Are there any pcbs out there without making my own? I don't have the capabilities to making them.

Hi Joshua, The 'go-to' part is possibly an LM386, it is through-hole and standard spacing so a small piece of stripboard or perfboard can be used, no need for a custom PCB. You could wire all three speakers…

Hi Joshua, How about something like this? http://www.ebay.com/itm/LM386-Super-MINI-Amplifier-Board-3V-12V-DIY-Kit-/171549481946?hash=item27f1255bda:g:vKUAAOSwofxUbUWD John

I will post an update, I am acquiring the parts required to build. I found a Bluetooth speaker to use the board so I can control from my phone. Are there any known bluetooth video options?

Hi Joshua,

The 'go-to' part is possibly an LM386, it is through-hole and standard spacing so a small piece of stripboard or perfboard can be used, no need for a custom PCB. You could wire all three speakers in series for it and use a single LM386 circuit.
Or perhaps google can provide an off-the-shelf pre-soldered amplifier but as I understand you wish to build it, so using an LM386 is not a bad option.

Great thank you, the reason for the pcb is the cleanliness I don't like the pref-board as it looks DIY. No One will see it when I finish unless I build its own case and different location and that's a possibility. It needed to be relatively small.
