what does are cars top out at for spl frequencies if i were to have my sub box in the trunk sealed off from the car facing into the car with the port on the drivers side, is it like 45hz or closer to 50hz?
each car is different. You will need to build your box and then tune the port as you meter it. Keep chopping it down in 1/2" increments until you no longer see an increase is SPL
