6,505,705) MOUNTING RINGS  
The GTO627 and GTO637 are packaged  
with two different speaker adapter rings.  
The rings will allow the speakers to be  
installed into various factory 6," 6-1/2" and  
6-3/4" openings. The metal ring can be  
mounted in many European vehicles,  
Japanese vehicles or vehicles with 6"  
speaker locations. The plastic ring can  
be mounted in many vehicles using 6-3/4"  
speaker locations or three-point mounting  
frames.

Note: The GTO8627, GTO6427 and GTO327  
speakers are designed to be installed  
under factory grilles. Consequently, no  
grilles are packaged with these models.
