Door Speakers - Max Depth 3" or 2 13/16"?

[Parker986]

I plan on replacing my 5" Bose door speakers with 6-6.75" speakers. Looking at three options, which will become part of a 3-way system. I would like to purchase before dismantling door, but I would like to be sure whatever speaker I purchase will fit.

I have searched and searched, and the results keep coming back with either 3" / 76.2mm OR 2 13/16ths" / 71.4375mm.

It really makes a difference which speaker I can purchase.

My plan is to modify existing baffle and drill holes in the back to vent. Can anyone tell me the exact measurements, or tell me the exact 6"+ speaker you installed so I can check the depth.

Thanks
