PA system?
 

I am looking for suggestions on installing a PA system on my 2000 Jimmy. I'd like to avoid installing a CB radio as my last setup included one, however I have no need for one. Just would love to have the mic inside the truck and the speaker up top. Any suggestions on what to use?

Thanks!

Id like to know to

i dont think there is a way without installing a CB or mixer, the mic would need to be going thru something to make it into something audible thru speakers, just get a small CB like a Midland 1001z i have one, or a cobra 19? i dont have a PA system, but u can mount a small speaker in the engine compartment i think, but what do i know =)
