Well in many cases the enclosure in a car can be smaller then for home use cuz you get "cabin gain" in a car...Originally Posted by john_draws
This means that your bass response will be extended cuz of the "room" your enclosure its in! (you actually could compare the combination enclosure-car to a bandpass enclosure, tuned to a certain frequency )
With the freeware prog WinISD you can give the parameters in from ur drivers and see the response for yourself, ect...
With a little experimenting you will really get some SQ out of ur car with them KEF's
