What size speakers in 2016 taco?

I have a SR dub cab and want to upgrade my audio but don't know what will fit the front and back... Anybody know?

 

Mines a Sport but think they are all the same. 6x9 front, 6.5 rear.

 

That's what I thought... Do I need to stick to this? What will happen if I put a smaller speaker in,? Or bigger

 

Bigger you will need to cut. Imo you really don't need bigger. For smaller I would recommend finding adapters so it's a clean install.

 

I suggest you replace the two front tweeters first with a quality set & crossover with quality speaker mounts and listen to awe full good change in sound and decide then if you even wish to go further.
You could also get the taco tunes front speaker & tweeter with crossover setup and mounts

Good luck
Cheers!
