I'm fairly new to this audio thing, and i'm reading about people needing adaptor rings.
I have a Deadcenter cycles fairing with Polk db651 speakers fitted and I'm going to change them for MM651 speakers, will I need these ''Adaptor rings''

 

If they fit the DB651's, they should fit the MM651's. Both are 6.5".

HTH - GL!

 

 

No sir you don't need adapter rings. These are only for stock fairings where the speakers mount from the rear. Your speakers will drop into the front of the fairing.

 

The adapter rings are mainly for the OE farings (batwing and shark nose) as they have 5 1/4 inch holes, so you either get another 5 1/4 or you use a 5 1/4 to 6 1/2 inch (or 7.1/7.25 depending on who your going with) adapter.

 

So adapter rings are needed for OEM inner fairings because they bolt from the rear? On lower fairings they bolt from the front? So adapter rings won't be needed on lowers?

 

you are correct sir...

 

^thank you, I am trying my best at understanding this all as I put my parts list together for my system.

 

no worries sir.. ask questions all you want.. better to be informed before you get into it.

 

I am planning to go with your previous suggestion UltraNutZ and going with 4 Polk mm651 for the inner and lower plus a slipstream amp.
