factory speaker size 99' tahoe

[TrailFiend]

i want to upgrade the speakers in my tahoe, which has the LT package and is a 2 door. i think that the doors take 6 1/2" speakers and the rear high mounted speakers are 4 x 10", but im not sure. also, there are tweeters in the doors...i need to know those sizes too. thanks

The doors are 6.5", as for the back they are probably 4x6. but if you don't mind getting your hands dirty and you have a dremmel or something similar you can fit 5.25" in there pretty easy. and if you don't want to do any cutting and don't like 4X6's you can always go with just 4". and as for the tweet I think its a 2" I have a Memphis Audio component set in my front door and with minor fabrication mine fit in there pretty easy.
