When you say reading bad, I assume you mean there is no continuity. If you put your meter on the lowest ohms setting and put the leads across and there is no change, you have an open coil. Many times when a speaker fails the coil gets hot and deformed. If you push down on the cone, usually with four fingers at even spacing, so you are pushing the coil straight down into the magnet gap. You should not hear any rubbing. Rubbing means the coil is deformed and you need to recone or replace. If no rubbing, use the speakers good coil and you have a single coil sub. There is a little extra weight with the dead coil, but unless you are a super audiophile you probably won’t notice, other than the spkr will not be as powerful
About all you can do if your really wanting to "fix" it, is tear it apart & completely recoil both voice coils. Otherwise you can just run it on the one good side like a single voice coil sub.
