If people/forum members/friends/little voices in your head tell you to upgrade your speakers, I will argue against bothering with rear speakers. If you must have rear speakers (fuck the passengers) just utilise the stock speakers for a bit of "fill". You don't go to a gig or concert and have the music coming from behind you, do you?

Personally I would save a touch more and replace the fronts with an entry level offering from say Morel (available from Westside). Awesome bang for buck speakers, will shit on most of the mainstream brands available locally around the same price point. Your stock speakers will not keep up with, nor blend nicely with a sub and you car will sound like complete arse.
