Do car stereos have built in amplifiers?
However, every car audio system requires an amplifier, whether it’s a weak, built-in feature or a separate, high-powered unit. In fact, a car stereo wouldn’t work without one. Most car audio systems and simple upgrades don’t include a separate amplifier, although many include a dedicated amplifier to drive a subwoofer.
What does a built in amplifier do?
An amplifier boosts the low-level audio signal generated by the head unit so that it’s powerful enough to move the cones of the speakers in the system and create sound.
Is amp better than head unit?
