well my box for 3 12's is in my build log. its a 91 sonoma extended cab. port towards driverside strait and there are no bends. no. but the 10's have been in in a accent and i forgot what the other car was. and the 15's were in a 03 focus. then a s10 extended cab. in the s10 lows were alittle better but still were not all that good.
and im using the calculator that is pinned in this section
