You will need a cb radio with a PA jack on the back, then the loudspeaker of your choice. Just make sure that you get a good speaker so that it dosen't sound like crap, and mount it uder the front of the truck, not under the hood.

 

like under the front as behind the bumper??? any specific brands you would reccomend

 

under the truck is probably a good bet but protect thats why mine is where its at under the hood if it wasnt id kill it drivein to school

 

any brands you would reccomend
