Depends on your vehicle. Certain models need additional parts.
They put a new radio and speakers in my car for about 90 bucks that's brand new buying from them buy from them they'll install it
I believe if you buy the speaker there, installation is free. If you're bringing the speaker, approximately $50 but that's an educated guess. I had a stereo installed that I had brought and it was like $40 but that was YEARS ago.
