So if I get that CB you guys have, and pick up one of those speakers from radioshack, I can have a PA? does the speaker run straight to the CB and works off that? Or does it require its own power source?

it runs straight to the CB. it required some soldering in a headphone plug so it could plug into the back of the CB

so the CB has an input for a headphone type connector, I can solder the wires from the speaker to that type connector, plug it into the back of that CB, and I will be good? Is there a switch on the CB to activate the PA?

the bc also has to be meant to handle pa out put

Id love to have a cb/pa setup. Keep an eye out though, i have had buddies harassed about impersonating an emergency vehicle or something like that

What do you mean by that? the bc

thats what i did and it worked perfectly
and yeah, the CB has that kind of input in the back for it
and its just a switch to change between CB and PA

I am so doing this!

Ya, me too, how much was that speaker and is it loud enough that my girlfriend will hear me in her house when Im in the driveway?

For my PA, I went to radioshack and baught some speaker wire with a RCA plug, and purchased a 3.5mm adapter, worked perfectly, no soldering needed, and only costed about 7 bucks....

12-Ft. RCA-Plug-to-Lugs Speaker Cable - RadioShack.com

Couldnt find link for adapter, but it should be on the same shelf in the immediate area....
