Why is my Honda crv rear speakers not working?

If the rear speakers aren't working on Your Honda CR-V it is most likely going to be some kind of electrical issue. Now this could be a large variety from this category but let's look at the most common. If You're getting power to the rest of Your speakers except one then it's likely there is a wiring issue. This is going to need a professional Audio mechanic to look at them and see if they need to be replaced. If it's both the rear speakers then it's more likely going to be a fuse. The fuse box under the hood will be the one You're going to need to replace.
