My outside Jensens are junk as well, so I will follow this topic thread with interest..
One was already blown when I bought the Trail Runner . . . had it replaced last fall under warranty . . . first use as I was sitting under the awning enjoying a cold Redd's Apple Ale with the radio playing at a very low volume . . . after about 10 minutes (and 3/4's of the Redd's Apple Ale
), one of those Jensen's started buzzing so bad that I couldn't stand to listen to it anymore!
I have already replaced the inside speakers with better ones, so I turned off the outside speakers and turned up the inside speakers so I could hear the radio outside, then went back to my lazy chair . . . and another Redd's!!
