Parts of the Car’s Stereo System
The head unit controls the overall system volume and audio sources in the vehicle. The amplifier increases the power of the audio’s signal, so it can move the speakers and create sound. Amplification is done by a preamp and a power amplifier. The speakers convert an amplified electrical signal into mechanical energy, which moves the speaker back and forth to create sound.
Types of Car Speakers
There are five main types of car speakers. Tweeters produce high frequencies and are the smallest type of speaker available. Super tweeters create the highest sound frequency possible. Midrange speakers create detail that tweeters and woofers cannot, as they handle everything in between. Woofers create mid to low tones, and are a versatile part of a full range speaker system. Sub woofers create the lowest frequencies, and are often very large.
Common Stereo Speaker Problems
One common problem with stereo speakers is a bad connection. This could be a bad connection to the amplifier, or other wiring connecting the speakers to the sound system. Check all the connections to ensure they are properly secure. If you experience a spotty sound from the speakers, they may not be grounded properly.
