5 1/4" Speakers

[BLUEKNIGHT911]

Yes this is from DJFanin, I have sent off a PM to him to see if he put the oem grills on...
I haven't given up yet! :roflblack:
I've also had the thought that cutting a slot into the vertical pieces enough for the speaker edge to slide under would give a little more clearance.
Rainy day here today, can't ride might a well modify! :2thumbs:

When all the speaker housing pieces are assembled that speaker ( or any other ) doesn't come close to the grill, so the grill has no effect ..... What PMK said about tires is true - the tire charts are Mathematical, however when the actual tires are made there are differences from the mathematical numbers ..... I don't think this relates to speaker size .... the metal frames may not be EXACTLY the same .... but any differences are going to be measured in " mm " way less than even 1/8th inch ..... also as I said earlier, there was enough room to add a 1 in. tweeter with an attachment bracket into the housing with the 5.25 in JBL .... Since you have the GTO 528 measure it against the Kicker ..... I doubt the size difference ( if any ) is what's causing your concerns ...... again good luck , keep us informed please ......

Success!
This is a post to a quick video of the steps I did to upgrade the rear speakers on my Can Am Spyder RT to 5.25" speakers.
