Replacing std speakers, not bose, to better ones?

[MikkiJayne]

You need a 3D printer, then anything is possible

This is a 6.5" speaker mounted directly to the D2 front door, rather than the 4.5" speaker which was mounted to the door card. Designed in Fusion360 then 3D printed







This is as far forward (out of the door) as a 6.5" speaker can go while still fitting behind door card, albeit with some fairly heavy mods to the door card itself. And the door. And the window frame Its 80mm deep and clears the window glass by 5mm. Clearance is clearance
