Need help with Stereo upgrade

Hello,
I have a 2008 VTX and want to replace the speakers, sub and amps. Please let me know what you think...Trying to keep the budget around 2K.

Speakers(6) - Polk Audio MM651UM or Wet Sounds SW-65i-B (Black)
Speaker Amp- Wet Sounds HT-6
Sub - Wet Sounds XS-12 S4
Sub Amp - Wet Sounds HT-1

Does anyone have experience with these components? Also, I'd like to add Bluetooth connectivity, so replacing the head unit is also an option, Anyone do this on a 2008? Advise or recommendations?

Thanks, I really appreciate any feedback!
