I have an 06 Street Glide that still has all stock stereo system. I recently blew a speaker. I am needing to know the size of the speakers. Are they 5 inch or 5 1/4 inch?

 

Audio part of this forum is where you need to be for that info, but I believe it's 5 1/4"

 

Get ready to upgrade lol... Check out the audio for sale section. There are stock speakers on there

 

They are 5 1/4" if you go with 6.5" you'll need adapters but be careful some of the manufacturers can't measure. I have some Metra 6.5 adapters that are only 6". You'll need the 6.5 to 6 3/4" adapters. If you aren't getting an amp try to find 2ohm speakers but you'd be better off adding an amp you'll be happier.
