The first and most obvious trick you can try to get to know your speakers is to listen carefully to them. Find all the primary speakers in your car’s audio system, play music without interruption, and listen closely to what’s coming out. When the speaker is working properly, you should be able to hear music at any volume.
When the speaker is turned up a bit, you may still be able to hear the music at a lower volume, but as you turn up the volume, it gradually becomes distorted and distorted. If the speaker is fully blown, then you won’t hear anything at all, or even soft sounds like crying, crying, or singing.
If you’re not sure about the quality of the sound you’re hearing, try holding a microphone with a equalizer to the speaker with levels of zero and well in between. If it picks up the obvious distractions, you should see them displayed in the same levels.
