Arsalan bhai, it is an absolute necessasity to place it on rear seat? I mean What if I place this box under dash borad. I see there is substantial space as there is no central console in Khyber. what you say?
u can put the spare tyre just facing the trunk door in vertical position.I have a same setup in my santro club n i can easily put my spare wheel too...
I donth think there is this much space in Alto or khyber to squeez tyre between phatta and truck. trunk wont close/
A 12" sub in sealed enclosure needs 1 cu.ft. enclosure minimum. for 10" volume required is a little less. clarion 10" subs require 0.5 cu.ft. sealed enclosure. if you can fit a box of that size in the front then its well and good.
