I never internally used my CB for such a purpose, but at one time I had a vibrant and penetrating base rig. I never cranked it up except in the early morning hours before the neighbors woke up. I thought I was being considerate.
One morning at a little after 3
o AM there was a very loud knock, and when I opened the door, there stood my neighbor from a block away. Her hair was in curlers and her house coat was barely on. She had a scowl that you knew not to mess with.
Her first words were, "Have you been on that %#&* radio this morning"?
I said, "Yes, why?"
She answered something to the effect, that my voice boomed from her stereo, even after she unplugged it, and it wasn't the first time.
I had an attention tone (paper clip fastened to the mike) that rang like a church bell, and it appeared that I had gotten more attention than I intended.
All this to say that indeed, a highly amplified CB will ruin your inconsiderate neighbor's music
and the tranquility of everyone around you for half a mile.
