I decided to do an upgrade to my front speaker system for my 2006 Accord sedan. Since removing the door panels is not entirely easy and I don't do this often, I'm wondering if there are any other maintenance/improvements that I can try and work on at the same time. I heard that it's a good idea to lubricate the lock and latch linkage with white lithium grease, but is there any other things that I should try and do while I have it off?

Thanks,

Jim
