As you may have noticed there are generally two types of mobile-automotive-truck pa speaker horn systems. Those that plug in to the back of a cb radio and those that have their own included audio amp and microphone units. The 50 Watt Variety of PA speakers are LOUD!
It is advised that if a PA speaker is used, that it be used in a positive manner. Using the PA speaker at Parades and in an Emergency might be two good examples of PA speaker use. Yelling at people walking down the side walk would be an example of non constructive of use of a PA system.
You may find other clever uses for a PA speaker while camping, hunting or just calling people to dinner.
Another important thing to note is some of the PA Systems above are 50 WATTS! This is an incerdible amount of power compared to those used on cb radios, which are usually around 5 watts or less. Even the 5 watt models are loud so you know 50 watts is LOUD! Please use responsibly.
