I'm going to order the pbr 300x2 with rfk10 awg power only kit and a set of Polk audio aa2651-a mm651 6.5 inch speakers.

My question is will I need to buy adapters to mount the speakers or will they bolt right in on my 2014 street glide.

 

Bolt in with the +14's

 

Thank you. Will I need to do drill the mounting holes on the speakers for a better countersink?
There is also a flash to be done by the dealer. Does anyone know the proper settings?

 

It all depends on how you want to mount them... Read the sticky at the top of the Audio forum and you'll get pointed in the right direction...sorta
