This is one of my winter mods that will be starting up soon, it seems due to Cincinnati weather not having a clue what it wants....
With that being said, Amazon has all three parts you list below:
P1650 speaker pr for 51.65 (something about Euro fit compatible or something)
T400X2ad 2 channel amp for 369.99
RF Bluetooth adaptor at 39.26
American dollars.

Does that sound about right or is there another site that I can get them from cheaper? 

Thanks for the info.  I have been trying like others to muddle through all the posts about sound and I am not doing any bag speakers at this time.  This is perfect.

Built the ultimate front fairing only system on my Stratoliner but can work for multiple bikes (I use all space in my bags). 1 pr Rockford Fosgate T1650 (6.5" speakers) and a T400x2AD mini amp (new rail boost technology has the most output and super efficient) They fit perfectly in the fairing and amp under fairing. Settings at 80hz HP (high pass) with a rockford Fosgate RFBTRCA Bluetooth adapter so you can connect your phone at will. The system sounds amazing and is insane. Big volume, a lot of detail in the music and ready for more. If you want to add speakers in the bags add the T400x4AD (4 channel).... if you don't have a front fairing the Batwing fairing is aftermarket as well as many others on eBay. Any questions at all text me or PM me.

hello just like to ask if the same controller for volume and changing song was able to be used again with this system

I used the little round bluetooth controller on my install. Connects great to my iphone and controls volume and track forward backward

That install looks good and the wires in the loom is neatly done.
