How to maintain the speakers in a Nissan Patrol?

I recently purchased a used Nissan Patrol and I noticed that the speakers are not producing clear sound. What should I do to maintain the speakers and improve their performance?

The first step would be to check the wiring of the speakers and make sure they are properly connected. If there are any loose connections, tighten them to ensure a better audio output.

Make sure to clean the speakers regularly to prevent any dust or debris from affecting their performance. You can use a gentle cleaner and a soft cloth to wipe away any dirt.

Consider upgrading the speakers to a higher quality brand. This can greatly improve the sound quality and overall experience of listening to music in your Nissan Patrol.
