Amp for a PA system.

I need to hookup an amp to my PA, because people can barely hear it. It is a small 5 inch speaker that connects to my CB radio, by an mp3 cord. Which should I get, and what is the best location for it?

I haven't had a PA speaker in decades but we used to use an amplified horn:

You could call Right Channel and ask...

I use a SPECO ASPC20 powered speaker and use it a lot. Plenty loud for my needs. An amp and a speaker heavy enough to handle it just isn't worth the effort or money. https://www.zoro.com/speco-technolog...iABEgJtnPD_BwE

Where did you mount it?

Behind the front bumper where the vac pump used to be located.

As a matter of fact, I keep one of these on the shelf. I didn't think the thing would last long considering the water, snow, salt, mud and everything else I drench the thing in regularly but it's been there 4 1/2 years now and still works like it should. Discovered one day it would even work under water but it wasn't very clear until it came to the surface.

Mount them pointed down, for two reasons
Keeps the elements out, especially if you go swimming, and helps the audio output travel better when you are on pavement
When you are on mother nature there isn't much you can do to get good audio out of them

Horn speakers are designed to be directed inline with your target for best performance which is why you don't want it pointing down and especially over a non-reflective surface. Speakers such as the Speco I use have no problem when mounted on their side with deflecting or draining foreign substances and are totally sealed. The one I'm running is living proof. Mine sits behind the front bumper pointed to the right which in my case is the least restrictive and therefore allows for the higher volume the OP is seeking. A buddy put one under the hood thinking it would be more out of the elements there. Bad mistake. Muted sound and the heat distorted the horn within days. His replacement sets exactly where mine is now and his vacuum pump is now under the hood. The only place more effective is to use a mag base and set it out only when you want to use it but that just isn't convenient for what most of us use these things for.

Yeah the designed for use loudspeakers are designed to be screwed right to the bumper
And are absolutely no joke

Whelen was always my go to, I also knew people that worked there so I am a bit biased
