Can you tell me the speaker size for a 2017 Nissan Altima?

The speaker size for the rear in a 2017 Nissan Altima is 6x9 inches with a resistance of 2 ohms, and there are tweeters on the sides. If the speakers are not working, first check the wires that power them and then check the fuse. Start with the fuse as it is likely the issue. To access the fuse box, locate a small seam or crack to the left of the steering wheel on the dashboard. Use a screwdriver or prybar to open it. Inside, you will find several fuses. Look for a diagram on the back of the panel you opened to identify which fuse to replace. If the diagram is not there, consult the owner's manual. Remove the fuse by pulling it out; if the thin metal strip connecting the two sections is broken, the fuse needs to be replaced. If the strip is intact, the fuse is still good. Replacement fuses are inexpensive, costing around $10.
