I found an audio shop that does them, and they seem to know a lot more about it than the local harley shop, everytime I go in they don't really know anything it seems. Only downfall is its an hour and half drive but give me a reason to ride
Just as an update on my end, I got the flash on Friday. It's not a night and day difference when you're in the garage but when you're riding, the stereo sounds much better, not just all highs.
I got my flash done but haven't installed aftermarket yet as of time restraints. But I noticed riding it is way quieter now with stock, can't wait to add the new components.
