PC205

Hello to all, maybe should be in another thread already but in a c205 coupe - cause of the door airbags - do I have to remove negative pole on the battery to remove door panel to install tweeters? I have seen some videos and it should be straightforward but the airbags there could be a problem. I have seen around that with key off the ignition there is no power on them - then again it seems risky.
Thank you!
