I have searched and searched and I cannot seem to come up with the right answer! What size are the stock speakers in my 08 STi? Are they the same as my 04 (6.5inch comps in the front and 5 1/4 in the rear)? I am trying to figure out what I need ASAP because the stock system is a joke and I want to know if I can put my stuff from my 04 in or not. Any and all help is much appreciated. Thanks!

They are 6 1/2's all around.

We were advised to change the Head Unit rather than the Speakers as the Speakers are supposed to be quite high spec and its the Head unit that is Lacking power

The speakers aren't the best I have ever heard, but they aren't half bad. I haven't changed them after swapping the head unit for a D3 and I have a pair of Polks sitting around the shop.

damn, the 08s get 6 1/2 all around!? Wish the 05s had that.

I was trying to avoid taking off the door panels. But it looks like my questions were answered. So it is 6 1/2 all around then. Well I can keep my MB Quart fronts but I will have to put my rears up for sale. Also I am keeping the factory NAV unit but upgrading something (sorry forgot the name of it) that will double it's output, as well as amping all of the speakers. Thanks everyone.

You can also call Crutchfield and get more detailed dimensions. I did and they told me that the opening clearance is 4.8", which means the magnets on many speakers (Infinity Kappa's for ex. at 5.0-5.2") will require metal trimming. The front clearance is ~0.9", iirc, so you may also need to use spacers to keep the grill off the tweeter if you use a 2-way (Kappas, again, are 1.3" for 62.9i's). The back clearance is acceptable at 2.75".

I am a bit of a quality sound freak so I have some pretty decent speakers that I already knew would require spacers etc (MB Quartz Q-line's). I will try and do a detailed write up with pictures when the stereo gets done over the next couple of weeks. Thanks again guys,

If you already have rears you like, why not mount them with a reducing ring instead of selling them? The difference in a 5-1/4 vs a 6-1/2 in the rear doors is not going to be very much at all.
