Hopefully this could help who ever is looking to upgrade.
After contacting many providers I decided to go with Garage Bagger Stereo.
communications with Chris is fast, right to the point and he answered all questions and made a sound system ignorant like me understands what he us buying what to choose and what not.
he recommended 3 options and I went with the following:
SounDigital 800.4 Amplifier
Rockford Fosgate DSR1 DSP
Hertz Audio SPl Show SV165.1 Pro Driver
Hertz Mille Pro 165.3
sql60 horns

my bike is a 2016 cvo roadglide. Boom stage 1 was installed and its day and night.
the sound is crisp clear and loud enough that I never had to go above half volume even when riding 100 m/h.
He sent me the preset files and changed it multiple times based on my request and he was with me every step of the installation.
now the actual feedback of the sound it self:
never thought I would get a sound this good on a bike specially after testing the stage two and 3 other companies products I was hesitant to order from GBS but I decided to pull the trigger. The first thing I noticed is with high speed I can actually hear the music clearly not just high noise of music. With my boom audio I always had to crank the volume to the max if reached 80 m/h and I wouldn't recognize the song. So for a person who is not technically expert on sorry to provide those insight but all I can say is WOW, this setup is beyond what I expected.

and truth to be told their customer service is amazing.

hopefully this helps any one decide to choose because I remember the headache when I was trying to decide.
For those thinking about stage2 from harley I tried it, it sounds amazing when the setting but couldn't hear a thing above 100, so save yourselves the time.

thanks
