Gunman has been kind enough to confirm that 6.5" can be accomodated in the front door of the santro.
Manual windows is not a problem as evident in the pictures provided by him in
this thread (Suggest Front Components for Santro (With Pics if possible))
So I guess I dont need to waste time or money building the enclosure building, instead I can use the money for some dampening for the front doors
Though im curious in relation to the above enclosure, how would it affect SQ /stage ??
