So I replaced all of the tiny 5.25" speakers with 6,5" DS-18 Pro 2ohm motorcycle speakers (the slim ones with outdoor ratings). Both sides required an adapter to fit the speakers into their respective locations. The 6.5" speakers for my speaker pods fit well within a 1/2"" (13ish mm) generic adapter bracket, as the new speaker magnet was too large for the stock well.Now, after mounting I needed a durable speaker cover, as previously my wife had kicked the stock plastic Harley covers, so I knew that just cheap plastic was not going to cut it. My first order did not turn out so well as the universal 6.5" speaker covers were just way too large. However, these 6.5" covers were a true 6.5" in size and fit snugly over the 6.5" speakers in place. The color also almost matches the Ember Sun Glo of my Road Glide and may look a little closer with some sun bleaching out in the elements where I park at work. This part was just a happy coincidence as I expected the speakers to be a brighter hue of red.After riding around with these for a few weeks, these have worked out perfectly. My wife says that unlike some other speaker covers we have tried, they did not jut out too far and into her legs and felt very similar to the stock Harley covers, given this cover's very shallow mount depth. Also, unlike prior covers, she has not kicked these at all (yet), which I do not know if it is because they are red and easier to see (don't blend in like black covers) or if she is just more cautious now, but I won't go back to using plastic covers for the foreseeable future. Even if I jinxed myself and she does kick them, these are very rigid and will survive a few kicks without much damage.
