Interstate radio

[Jims99]

I'm new to the interstate world. I figured out how to run everything, but can't get stations to come in good. Checked all connections to antenna and still not good. Hook up iPhone and sounds great. Also want to know if there's an upgraded speaker to put in. I have one that's not sounding good. Also the helmet set, does that allow you to talk to passenger or just for radio and cb. I don't have intercom sets and not sure if I need them. Thanks JIm

Follow this for replacing the front and rear speakers.

These are the speakers I used. Just about everyone recommends these Polk DB501's
