hello everyone i've done alot of research on the rear speaker fitment and it seems like there is two different replys for the question about the size that would fit the most i've seen is 5.25 is the speaker that would fit but there were some that said 6.5 would also fit (not using any adapters/baffles) i'm a bit confused which is correct? or does it matter between the model years? i have a 2009..also is there a speaker DIY for TC anywhere on the web? i've been trying to search for that too...thanks

 

either would work with the adapter. i think the original size is 5.25 though?

 

The stock rear speaker is roughly five and a half inches. With a baffle, you can easily go up to 6.75" with no other modifications.
