Unfortunately it happens a lot with PA speakers.
The PA speaker needs to be a long way from the mike. It can even cause feedback if the PA speaker is on the outside of the vehicle.
Finding a good spot that doesn't give feedback can be tricky.

I had a mini Hustler ages ago.
Only about 18 inches with centre load and mini mag-mount base.
Range wasn't to great but it looked like a taxi antenna.

I like the charcoal but it's a bit dark as I have my monitor dimmed for most web pages being light or white colour so I use the defpom style.
