Speakers and Amplifiers


The other main components of a car stereo system are the speakers. Not all factory sound systems ship with a separate amp, but they do all come with at least four speakers. While you can upgrade them without installing a new head unit, you’ll probably be disappointed with the sound quality. Unless your vehicle came with a premium head unit, it probably won’t be able to properly take advantage of upgraded speakers.

On the other hand, installing better speakers can provide you with more room to upgrade the other components in the future. Even if your current head unit can’t take full advantage of the situation, you’ll have the option to put in a better head unit or an amplifier in the future.


On the other end of the audio spectrum, you can get a lot of mileage out of upgrading or installing a subwoofer. Most vehicles don’t come with subwoofers, but the ones that do are usually pretty anemic. If your car or truck didn’t come with a subwoofer already installed, the easiest option is to look for a unit that includes a built-in subwoofer.
