Drive outdoor blue tooth speaker from analog cd player

I ended up getting the transmitter that has a range of 65 ft for $30. It does seem to be reliable out to about 50 ft, which is plenty for my application. Only complaint might be that I can't turn up the speaker louder than the volume in the trailer, which I figured would be the case. It's a decent speaker for $15. So far it works well. Thanks for the input folks!
