Could you tell me the speaker size for a 2017 Nissan Versa?

The speaker size for the front and rear doors in the 2017 Nissan Versa is 6-3/4 inches. If the speakers are not working, check the fuse box. To access the fuse box, look to the left of the steering wheel and search for a small seam or crack along the dashboard. Use a screwdriver or prybar to open it up. Inside, you'll find several fuses. The back of the panel you opened will have a diagram showing the purpose of each fuse. If the diagram is not there, you can also find it in the vehicle's owner's manual. Once you determine the fuse you need, simply pull it out. If the thin metal strip connecting the two raised sections is broken, the fuse is bad and needs replacement. If the strip is intact, the fuse is still good and can be reinserted. Replacement fuses are inexpensive, costing about $10.
