Any post's about upgrading the F6B Audio is appreciated. Many may just view the posts without comments and get the info/ ideas. I have read Jimmytee's post several times as well as others and is good to see the many different approachs and outcomes. I have ideas of my own and working on an amp, speakers, sub system, using the stock head unit. I will be posting a big write up soon. If you look at Jimmytee's post on page 3 , Lacoocheeboy (Ted) used the same Kenwood System you have and has added a subwoofer 6.5 Kicker with Rockford Fosgate amps and has a great sound. He also uses his phone - Bluetooth for music. Thanks for sharing this as many riders are looking for better sound and Bluetooth.
