I'm a new CB'er but I understand that using an amp with your CB is not permitted in the states. Of course, there are many laws on the books that are not enforced and many that are outdated and many others that are simply no longer enforced (like spitting on the sidewalks). Soooooo, use you an amp with your mobile CB? Why? What's the main benefit you're deriving from it and would I benefit from using one?
