I just purchased a 1997 GT coupe. It has a crappy aftermarket stereo I would like to replace and it has all original speakers i would also like to replace.

The car has the 8 speaker "premium sound" option according to the original window sticker.

- I would like speakers that fit into the stock speaker mounts and locations.

do i need to replace all 8 or can i replace just six?

- also i would like recommendations on inexpensive stereo that will allow me to use the controls on the wheel and also not have to buy an amp for the speakers. also with an ipod and/or aux input on front.

any link and/or help will be greatly appreciated thank you
