I have a 2013 21V which currently has (4) 6-1/2" speakers on the tower. The two on the sides are Polk Audio and swivel and the two on the top are roswell and are fixed. I'm looking to replace all 4 with the REV-10 speakers but don't know what to do with the mounts. Do I need to get the swivel mounts and attach to the tower in a new spot or can the W/S cans attach to the existing mounts?
Thanks for any help
Steve
