My favorite part is bass, subwoofers aren't easy, sure, adding a decent subwoofer to a system to supply more bass is no big deal, but getting the best possible sound out of a subwoofer IS.
Now, if one subwoofer is good, are two or more subs even better??
Of course it depends from the car size, type of music, how old you are

etc... Anyway, if the car is not in every day use I think more subs are even better.
So here we go, what about 2x15" or 4x12" or 2x18" I'm still not 100% sure, but I have one of my old setup already tested-
and it's this one
another shot
nearly whole setup
Yaeh, I know, question is how to place all of them inside boot. Well I'll manage somehow :-/ For me most interesting are 2x18"- so will take this decision soon
