How do car amplifiers work?

Electronic transistors typically amplify the audio signal in a car audio system. Using electronic components such as capacitors and resistors, an amplifier boosts an inaudible line-level signal from your head unit so it’s powerful enough to move a speaker’s cone back and forth to create sound.

How can you tell if an amp is blown?

These are listed below:

  1. There is a noticeable distortion in the sound.
