Does anyone know the specifics on why Harley has deemed this kit non-compatible with FLHTKSE with Stage II Audio? The only thing I could imagine was an amp storage issue but the FLHXSE fits everything in just fine; two amps in fairing and one in saddlebag. Why would the Limited have more difficulty? Could add the amp to the saddlebag same way or mount to bottom of tour-pak.
They show both an 8/4/1200 and 6/3/900 watt config for Stage II and you can install this on everything else except the CVO Limited and CVO SG with a tour-pak. Fine if its a legit technical thing but I just don't like it when Harley simply says, no you can't do that and never explains why. Besides, it might not be technical but rather marketing-based; to try to push you to a different model. Of course, just for the speakers, install kit and amp you are in for about a grand. That's a lot of money to spend on a "it might work" experiment.
There is precedent for my skepticism though. I was told I could not install a CB (bike to bike) module or lighted switch kit on a 2017 SGS because it wouldn't work with the BOOM software version for that model. I have to use the new Sena 20s. And so on. Yeah...it was plug and play and switches work without issue.
