Nope. The rear speakers are 4" just like the fronts, but they are amped. Each box (one on each side) has its own amp. You are correct about the speakers above the rear window, but they are not quite tweeters. They have some midrange play in them.

BTW not all 95's have a 6 speaker system, but most do.

 

For the record I bought a pair of Diamond Audio 4" speakers for my 86 4Runner dash mount, and love them. Great sound, and fairly easy to install. Diamond audio is one of the TOTL brands too.

 

Wait a minute. I know the fronts are 4" but I thoguht the lower backs were 6x9s? If not they must be 6.5s cuz theres no way they are 4". Mine sound like wimpy 6x9s to me. Does anyone know whats in the upper back. My dad told me to ask for stereo stuff for christmas so I want to know the sizes and the best speakers to put there. If the backs arent 6x9s or 6.5s Im going to jerry rig some cuz I need some for of good bass that arent subs

 

I'm pretty sure that there are 6x9's in the back. I know that some people have made 6.5's fit in the back before. I have some 4" MB Quart's in my pickup. They are nicer than most any other 4's I have heard, but they can't handle the bass in alot of my cd's and some songs on the radio when I have the volume high. If you really wanna make a big difference in sound, get some kick panels and put in some 5.25's or 6.5's. I have an entire system sitting in my room waiting to go in my truck. One of my favorite pieces to my system are my Focal 6.5's. I have yet to hear them in my truck, but I know they will sound amazing!
