HAM/CB shared external speaker

[Vegas_Nick]

^^ You can do that, but you risk audio distortion. I built a couple of these a few years ago. Really no different than a studio mic mixer going to a single PA system. I ran into issues because I was feeding it into the truck aux port, so impedance matching and such were a bear. I built my own amp and built the mixer for door speakers in my rig. Again, not happy with it so I just went back to door speakers for ham radio and the CB has its own.

Tried finding it but all I have left is the PC design drawing.

Testing one of the first builds.
