2015 CVO Limited currently with a Boom GT 6.5 and the J&M Rokker 800w 6 speaker kit installed by J&M (I think) by previous owner. The bike came from (then) Rossmeyer HD in Daytona and the installation looks professional. Probably not the system I would have picked but it's there and sounds good enough.

I bought a Boom GTS from a forum member that should be here in a couple of days. It was removed from a 2023 Tri-Glide.

Will the Boom GTS unit need a dealer flash for the aftermarket J&M system? I called J&M and they weren't sure. Who besides the dealer can flash the system if needed?

Thanks!

EDIT: I think it's equivalent to this system https://jmcorp.com/JMC-ROKKER-1000XX...de_p_1571.html

 

Anyone, Bueller????

Installed it today and everything is working. The volume is extremely high at the half way setting.
