I have a 2011 Street Glide 103. Stock stereo.
Getting ready to install the 7.25” J&M High Performance Rokker Faring speakers in my faring. Soon I want to install a set of speakers in my bags, at that time I will do a four channel amp.
My question: I understand the dealer can flash the stereo so the fader feature works on my bike. If this feature is turned on, does the system then divide the watt output to four channels instead of the current stock two? i.e. 20 watt output getting divided by four instead of divided by two? I ask this because I am considering having the system flashed when the bike goes in for the factory recall, but it will be some time before I actually start running four speakers; I don’t want to lose any wattage to the fronts right now….

 

It will not split the output power.
Your rear speaker outputs are already active.
All the flash does is activate the fader

 

let us know how they sound

 

Thanks for the input, much appreciated.

 

The Rokkers will sound better than the stock speakers but won't really perform to their potential without an amp. The difference is night and day.
