what size are the rear speakers
 

ive been searching this site for answers but cant seem to find it. im looking to upgrade my stereo system because the four speaker system that comes on the base model really sucks. ive looked around the car and saw that there are ports for rear the speakers but when i fade the radio to the back channels i dont hear anything. I would like this to be my very first upgrade because i just cant stand how the factory radio sounds with only front speakers.

Be prepared to run wire to the rear speakers if you want to do that.
I would advice against it since the audio stage in this car is small to begin with, upgrading the front speakers (two) and tweeters (two) will be a large change. To answer your main question, I believe the size to go with is 6.5" speakers for front.

I to advise against using rear speakers. Also this has been asked a lot the rears are 2.5 or 3.5 inch forget which one right now.

they are like 3.5" and if you add a pair, they do absolutely nothing. I have always sworn by rear speakers, but with what we have to work with, the others are right, leave them out and just upgrade the fronts.

I put in a set of JL Audio CS350's and they fit perfectly. I run them off of the rear channels of my head unit and crossed over very high so they dont distort. They don't make a huge difference, its subtle but I feel they add a bit of re-inforcement without disrupting my front stage. Again, its subtle but thats the point of rear fill.

I have turned them on and off during numerous tests and I still keep going back to turning them on because I feel my sound system sounds more balanced. It might just be my imagination but I swear they help blend that sub in the back a bit making it even less localized.

thank you for all your support, i was also wondering how hard it is to take apart the pannels to get to the rear speaker inclosure. right now im still not comfortable in taking my doors and rear panels apart but would like to set up a decent sound system in the future. such a beautiful car but very mediocre sound. im trying to plan out my upgrade slowly so im trying to gather up as much information as i can. thank you once again for all your help.
