i have planned to use right side coin box for vent and i will install computer cpu fan behind the air vent in the plastic pipe.
for left side i have to cut the dashboard maybe depending upon the space behind it.
by doing this the blow from the center vents will decrease.
Another option is by making holes in the air box behind dash board and taking two pipes out from the middle to the back of hand brake and installing armrest with ac vents. this is just an idea, it couldbe diffficult but not imposible.
lets see
