Brother, it’s just not going to happen. Best suggestion is create a small budget (3-500.00) and replace the amp in the fairing and your fairing speakers. If you get creative enough and shop the for sale forum you can scoop up some damn good deals.
But what your wanting to do just won’t happen. And even if you could piece mill the crap out of it your not going to like the sound.

 

Thank u Tes. Much more eloquent and effective than my attempt.

Can you unplug the boom harness and bring it to stock no boom configuration?
I have a similar scenario as far as boom amp and such but it pertains to a sidecar (6 speakers 4 amped 2 not) if I unplug the overlay harness that feeds the boom amp I can go back to stock wiring config then I can run aftermarket amps. At least that is my plan once I get my fairing speakers bought

 

As simple as I can put it fellas; you either use all boom amp-speakers or NONE AT ALL. It’s truly that simple. You can keep the headunit but there no magic potion to do anything else EXCEPT replace the boom speakers with the kappa 2 ohm speakers. That’s a better sounding speaker than the factory boom but not by much.
That’s it in a nutshell.

 

I am trying to bypass my boom amp wiring without actually removing it.( It's a sidecar rig and I want to be able to return to stock in case I sell it later) I already have amps and rear speakers, I just need fairing speakers.
