With that in mind, people often get confused as to thinking what are actually the important parts and features of a car audio system. So, let’s read more and find out the details of a car audio system.

Car Stereo Sizes

Car stereo sizes are expressed by single DIN and double DIN label. ‘DIN’ indicates the size of the in-dash unit or the ‘head’ unit. The measurement for single-DIN and double-DIN is nearly 7″ in width with 2″ and 4″ height, respectively. The stereo depth may vary depending on the audio system. So, it is better to measure the depth stereo cavity in your dash.

If the amplifier is large, mounted it in the car‘s trunk. It is capable of supplying power to one, two or four audio channels. There are a few specifications of an amplifier.

Amplifier Specs to Consider

When an amplifier is installed, it lists the RMS power and the peak power. RMS is the steady power level that the amp will produce. Peak power is the maximum power that will be produced by the amp in short bursts. The power rating on the amp should match the car speakers to avoid distortion or damage.

  • Low-pass filters provide better low-frequency bass sounds.
  • High-pass filters provide better high- and mid-range treble sounds.

Speakers are basic audio devices. If you are not satisfied with the sound level, make it more powerful with an amplifier. But make sure that the amplifier matches with the speaker’s power level to prevent speaker blowout. Car speakers are of two basic types:

Types of Car Speakers:
