Question on speaker replacement

On a non JBL Base unit, Can I replace the door speaker without replacing the tweater? Will the stock tweater still work?

 

Alright maybe this will help someone else 10 years from now. Replaced both front and rear speakers. Seems like if you destroy the OG speakers you dont have to remove the rivets and just insert new speakers in the factory riser. Front tweeters still work. There is a wiring diagram but there is no pink wire in front. I bought some pretty cheat Pioneers and Geavess brand speakers. The Geavess speakers had a bigger magnet. They sound ok but honestly not sure how much better than stock. I upgraded to an android head unit from China and I am running a base tube. Sounds good when inside but not supper loud when outside the car. Im just playing with this car for now so dont want to invest too much money in it. I was hoping to keep the stock speakers for when I sell it but I dont want ot have to buy a riser or fabricate a piese of wood to mount the speakers. I am amazed how good the stock speakers sound though with such a small magnet.
