I have a 2012 FLHTK that I just put a Biketronics 4180 amp, 7.1 speakers in the fairing, 6.5's in the lowers, for now I put some Alpine SPR-60 speakers in the pods. I ordered an aftermarket install kit & Bill sent Me an empty pod to try.
I have a Harley heated hammock seat which is a large seat. The stock pods rubbed the seat & the Misses needed a little more room so I added the Kuryakyn 8973 tour pack relocation kit. The Biketronics pods are way bigger than the stock ones but everything clears fine. Now I have to decide 6x9 lids or 7.1 pods, well maybe both after I get My 107 build done. decisions decisions.
