I took a quick look at the rear deck speakers to replace them. Do the grills pop off or do I have to take the whole rear deck out? Also is their a way to get the code to the radio if I don't have the card? Thanks for the help!

 

the only way to get the code for that radio is through the dealership. they plug it into their comp and get the code. the only way to get the rear deck speakers out is pulling the deck off. it's not hard really. here ya go
