:quiet: You've probably seen me comment on this before...
Concentrate on better front-end for better sound quality :approve:
6x9s are only funky for those who aren't old enough to have a license
Best example- If you go to a concert wouldn't you prefer to be closer to the stage?
The rear (std speakers or uprated
Co-axil's) will run perfectly off the HU
Rear speakers (beside your seats) only provide rear fill.
If they are just as powerful as the components in the front you AND your rear passengers will get a lot of interference & "noise" from having a mixed sound stage
Component speakers in the rear will require more work than just IN & OUT;
- Modifying the doorcard for the tweeters
- "Aiming" the tweeters correctly to give the best sound stage
- More than 1 set of components adds to a more complex sound system, requiring more work & labour if you are paying for fitting
Just my opinion from what I have learned (so-far) from my local ICE installer over the years
My setup...(in progress)
Alpine HU & Digital Processor
Focal Components in doors
Tweeters mounted in A-pillars
Focal 4 Channel amp bridged to run comps
Focal Co-axil's in rear doorcards (running off the HU)
Focal 13" sub powered by a Focal mono amp

At the end of the day it's all up to yourself & your budget
Good luck
