Built the ultimate front fairing only system (I use all space in my bags). 1 pr Rockford Fosgate T1650 and a T400x2AD mini amp. 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).... Pm me if you have any questions. This silly phot restriction size is prohibiting me from posting pics.

I just put the Kuryakyn road thunder sound bar and with my windshield its great sound even above the 85 mark.

You can see the original post with pics here. My system will play super clear all the way to 90mph.
