My CB radio works fine plugged into the 12 volt, but my fuse blows when I included my 100 watt PA speaker. Is it possible for the CB unit to be powered straight to the battery? Is there any other recommendations?

 

pa is to big for the audio circut,get a smaller wattage speaker it will work just fine,

 

no can do, I exchanged the 50 watt, too quiet, 100 watt is just right. How do most people hook it up?

 

well, if you really are set on having one LOUD a$$ PA unit, you can pick up a crappy el-cheap-o car audio amp. you will just have to splice the PA speaker wire to one of those audio video wires and run power to the amp and a remote wire. Its not that difficult. If you go this route, you can get an even louder PA...up to whatever you can find a horn for and the quality of the amp doesn't really matter because your only going to be pushing no more than 200 watts max.
