DON'T DO THIS!
Absolutely ZERO point in 6x9's AND a sub. Unless all you want it low-range.
Get yourself some decent amped co-axials up front, and a small sub in the rear/boot.
I disagree - sitting in the back in my car you'll get far more bass, even if the sub is turned right down. I only have door speakers, tweeters in the pillars and sub in the boot and the balance is right.
Call me daft, but a) who wants JUST bass when listening to actual music, and b) who sits in the back of their car?
i'd personally go for comps up front and a sub in the boot.
ask yourself this, do you stand with your back to the band when at a gig or are your ears on backwards?
My vote goes for this too (it's what I've goti'd personally go for comps up front and a sub in the boot.
