Ok here is some mock up teasers by CustomerSpeakerPods
Coupe will have a dual 6.5 and tweeter option

 

if ur gonna be mass producing these make sure they will work in a balt with the window crank

 

Yes will be an option a user will have to inform of during purchase. Door's with window cranks will have fewer options than ones with electric windows.
Example electric windows could do 6.5 , 4 and a tweeter mount or dual 6.5 and tweeter or maybe an 8 alone. While the manual window doors will be limiter to a midbass and tweeter only.
