How do I remove the cover panel over the Blose Sub? Do I have to remove the whole back panel, or can I just take off the speaker cover??

 

just pry the speaker panel out.

try just using your fingers and prying off from the top left corner.
if you can't work your fingers into getting it off get a flat head screw driver and something like a paper towel to wrap it in so you dont scratch your cover. then use that to pry the panel off.

it's pretty easy to do. i used a flat head the first time just because i thought it would be hard but i have done it many times since with my fingers to adjust settings for my amps which are in that compartment.

But if you want to take the bose sub out, the entire panel has to come off.
