For reference I am using a NAV-TV bluetooth source to feed a BT4180 with HAT 5x7's in the lids and BT Titan II 6.5's in the lowers. Vol +/-, play/pause, track up/dn etc. is all with factory handlebar controls and a SWC module.
What NAV-TV bluetooth module are you using? (Part #)
StreamBlue interface Part# NTV-KIT510. It's a bit expensive but works great. Mike at Biketronics sent me some info on one that he has been working on as well, it is BT344. Not sure if it's a standard offering yet. If I hadn't already bought the NAV-TV unit I probably would have gone that route. Can't speak to the performance but Mike and Biketronics have been great to deal with and their other products are top notch.
I put Biketronics speakers in my lower fairings and 6x9's in the saddle bag lids with a soundstream 400w amp in the left saddlebag and it was stupid loud and clear. Loved it! Way louder than my father n laws stock ultra limited.
Unless your willing to give up all of your bag space to large speakers and amps you will likely not be satisfied with the result. I put a 4 speaker system on mine this spring and 80% or better of what I hear on the road comes from the the front speakers in the lowers. I have to turn my head a little to hear the rears. I don't particularly like having lowers on my king but it was the best option for me to get quality sound without an aftermarket batwing.

It wasn't cheap by any means especially utilizing OE painted lids and lowers but it looks and sounds great. If your interested in more detail just let me know.
