Will upgrading your car's speakers really make a difference?

Unless your luxury automobile already features high-quality car electronics, upgrading the factory-installed speakers is one of the easiest and most inexpensive ways to improve the crispness of an audio system's sound. Enhance the bass with a more powerful subwoofer, and up the volume with a quality amp. Even good OEM speakers are not built to last as long as aftermarket upgrades. For a relatively small investment, upgrading the speakers can even increase the resale value of your car.

What are the benefits of upgrading your car stereo?

Aside from better sound quality, high-end systems also offer a variety of functional upgrades to most stock stereos. This may include Bluetooth connectivity, auxiliary hookups for smartphones and MP3 players, GPS capabilities, a touchscreen, and voice commands. Some units come with audio and video perks, including the addition of an in-car DVD player, multi-CD changer, and satellite radio connectivity.

What are different types of in-car GPS units?

Many different manufacturers, including Garmin, TomTom, and Magellan, make in-car GPS units, but there are only two broad types of GPS units to choose from: in-dash units and external units. An in-dash GPS unit is a much more substantial and permanent upgrade to your vehicle. It involves removing the stock stereo and replacing it with a GPS-enabled one. External GPS units are easy to connect to your vehicle's sound system for voice directions, and they typically mount onto the dash. Because these units are removable, you can transfer them from one vehicle to another as needed.
