question ... i just purchased two R F kits... plug and play... amp and speakers for the front and new two me bag speakers.....will line levelers override the harley no base programming when running? this is the kit for my 2017 SGS

 

the line levelers from biketronics will, or you can find someone that knows how to re-flash the head unit and has the proper tool.
m

 

so ... one leveler for each set of speakers?

 

One Line leveler for each pair of speakers only if your head unit is setup with fader control and you want to use it. If your head unit has no fade setup, 1 line leveler with Y cable RCA's to feed all 4 amp channels.

 

 

great thank you...... ill go that route Car toys probably can
