please please no 6*9's if you gonna get a sub.

(Actually
dont get them even if you arent gonna add a sub)
just amp your front and rear GTO527's and you should be good
6*9's need an MDF rack.this ends up taking away all the height in your dicky .PLus you have a getz whose seats double fold.with that silly MDF rack you will not be able to fully utilize that neat (double fold) provision!
its an other matter that
i believe the 6*9's screw up your soundstage too
