I have a 5" PA speaker for sale that I originally got from 99offroadrngr. I believe this is a 5 watt PA, but I'm not sure.
This is plenty loud to be heard while driving, I recently upgraded to a 15 watt of the same size, so that's why I'm getting rid of this.
The wire is spliced near the connector but works just fine.
Asking $15 shipped
