I know this is a little off topic but im wiring a pa system into my blazer. I wired the P.a. speaker to the radio and it works so I hooked it up to my cb pa port and it works but its really quiet. I used a set of broken headphones and the wires to hook up the jack to the back of the cb.(because I needed the plug in jack) Then I hooked that up to the back of the cb.Is it a possibility that im using too small of a guage of wire and its not letting it get loud enough or do I have bigger problems.
