Most original factory sound systems in modern cars include one or two built-in subwoofers. But 10 or 15 years ago, this was not common. Therefore, you will probably need to add one. Even when present, factory subwoofers are often weak and non-impactful. Installing a new one can provide a much deeper and fuller bass experience.
What is the difference between coaxial speakers and component speakers?
Tweeters and midrange speakers are usually combined into a set, either coaxially or separately.
The classic format for rear speakers, 6×9, provides slightly more bass (sound resonance) than a typical round speaker.
Coaxial speakers have a midrange speaker as the main, with a center-mounted tweeter. This can be a bridge over the midrange speaker or mounted centrally through the midrange woofer cone. Most vehicles manufactured before 2000 use this type of system almost exclusively, and it is still used in many new vehicles.

The component assemblies are similar to coaxials, but instead of the tweeter being mounted next to the midrange speaker, they are separated. These sets are always connected with a crossover, which attenuates the lower frequencies that can damage the speaker. Crossovers must be compatible with the speaker model as they are tuned specifically for that set of speakers. Mixing and matching different components can generate unsatisfactory results.
