I've heard 1-1.5" for the batwing, have seen several pics, and know it'll be thick enough that outer fairing will hold it in place. Think I'm good there. What about the lowers? I just recently saw UN said poly-fil could be over done in lowers. So how much should be done in the lowers? Is it better to error on too much or too little?

my opinion as well. Use Polyfil and wrap the fairing speakers like a big white cotton ball. You WILL notice that difference.

Anyone's
Just finished up my SS 4.520D amp and Biketronics 6.5 speaker install in my 2012 SG. I used Polyfil but suspect I got the wrong Polyfil. The stuff I got is like a foam pad not the soft fluffy stuff. Haven't tried to re-install my batwing yet, but suspect its gonna be tough!
Any thoughts on where the amp, Loc80 pr wiring is before I reassemble?
Thanks!

Looks like your amp will hit the fairing B4 the PolyFil will. I put the Baffles over my speakers and had no trouble. Can you move the amp back where it is flush with the HU??
