Ok I am learning a lot! But I am not quite up to par on my vocab and all.


What does this mean.  +12V Side with the capacitorto radio  

 Black Ground +12V to battery


Does this need to be put in line with the power cord of the radio or on the alternator??? And is it good to have even if you have no idea if your radio has noise or not?


So the real question is how do I know if I have noise or not. Cause as of now I have my radio wires to the junction box under the dash.   THANKS!!!!
