What size are the speakers in the back? Ours sound nice, but I'm going all out and I plan to get 4 nice speakers to replace our stock speakers. I'm also installing a JL W7. I'd like to do a custom setup, but I don't know where to get it done?

 

They are 6.5 inch man.

BTW....if you are goin' for all out sound and clarity...in this car (b/c its not a hatchback) you might want to consider a decent 10" sub in a good sealed box or a series of 8's if deep bass isn't your thing. I have a Bazooka tri-sub and I love it. deep, clean, and punchy bass!

Just my .02
