What type/size enclosure do you have now and what don't you like about it compared to your buddies? Are they the same subs with the same amps in the same vehicle?
All of the computer programs I use (and have tried) can only calculate a certain alignment in an anechoic chamber. Unfortunately we don't drive anechoic chambers and every vehicle is different so you would need to know the transfer function of
your particular vehicle in order to have an idea of how that sub will respond in
your particular vehicle! This still will not be perfect and if you have a passenger or 2 everything changes anyway!
