I have this system secondhand and it came with no remote control. The manual says in order to do either of these things, I need a remote. The center speaker is way too loud and the subwoofer isn't turned on at all. Someone please help. I have a universal remote from Sony, RM-VLZ620, but I can't find a code to operate the system. I also have a universal remote that came with my TV, Samsung BN59-0141A. I have no idea what to do here, and I really don't want to spend 40 dollars on a replacement remote from the internet.
