my stock camry comes with 2 tweeters, and 4 6X9's - 2 in the front doors and 2 in the rear deck.
i have 2 install options that im looking at
1) 2 6.5" component sets in the front and 2 6.5'' full-range speakers in the back (dont want rear 6 X 9's to overpower front setup) with 4-channel amp
or
2) just keep the factory tweeters in and replace all 4 6X9's and 4-channel amp

the second option is a little more cost effective....but i was wondering which setup will sound better and by how much, and will I run into any problems mounting smaller 6.5's in the 6X9 locations

 

personally i would stick with the 6x9s,allthough 6.5s will prolly do the same job,Just make up a 6x9 mounting plate to mount the 6.5 to.

 

6x9 will be a very simple install and you can set up your deck and amps to not overpower your front speaks

 

I'm a big fan of cone area.....a 6X9 has basically the same area as an 8" driver so if you mount them right and seal up the doors properly, your midbass up front will be pretty strong......

As for the tweeters.... ......hook them up and if you have to, blow 'em up.....

A decent set of tweeters could set you back around $100 or so, raise the soundstage back up and handle the amp power no problem......

Nice car for audio....bet it would sound pretty good in there with just the 6 aftermarket speakers running full-range off the amp.....

HTH

 

Where did u find out the stock speaker size in the Camry front door is 6x9??...They're definitely 6.5" speakers up front behind the door panels if your cam is 1992+ model........

And for the rear speakers the size isn't truly a 6x9 hole, but its fairly easy to to make a 6x9 work...

If you need help getting to the stock speakers check out this link for repair manuals on whatever gen cam u have: http://www.camrymanuals.com/

Good luck..

 

I also must question the 4 6x9 in a camry

at the moment I am not aware of a 6x9 that sounds good (just because I have not looked a that size as an SQ option) but there are MANY 6 inch drivers that sound excellent. I generally make mounting plates out of plywood or MDF (i.e. http://www.crutchfield.com/S-6cY2R2JsEHO/cgi-bin/ProdView.asp?wm=fp&I=065SL80&g=51900 ) and mount a driver I have or like into a hole that is too big.

If you find a good SQ 6x9 clue me in
