If you care about volume, an amplifier is still the component you need to add to your system. You’ll probably need an amplifier with speaker-level inputs if you’re leaving your stereo from the factory, but some premium factory head units come with line-level outputs.
It’s easy to overload your speakers when you add a powerful amplifier to a factory sound system. With that in mind, upgrade your speakers if you want to increase the volume to the maximum.

The most important thing to look for is a wiring harness that is specifically designed for your vehicle. This harness connects to the factory wiring, so you won’t need to cut any wires from your car’s stereo system.
Some of these wiring harnesses are designed to be connected to a new head unit, which means there is no need for wiring. This is the easiest way to install a new head unit and ensures that you can reinstall the stereo from factory whenever you want.
