Has anybody replaced their outside speakers with a better sounding speaker? I was thinking some marine speakers might be better. Mine sound worse than a couple of tin cans on a string. Also the volume is very low compared to the ones inside but that could be because they are ten feet in the air. Am I the only one thinking that the placement up there doesn't make sense? I would prefer them mounted low so I can keep the radio volume low and not impose on my camping neighbors. I have a Bluetooth speaker I use now off my phone and that's great but there are times when the outside ones would be easier to use.
