The receiver is essentially the brain of a car audio system. That’s why it makes sense to call it the head unit. It’s the head unit’s job to read CD’s and pick up radio frequencies and then send that information out to the speakers. Receivers vary in price range from under a $100 to well over $1200 depending on features and quality. If there is extra money in the budget don’t skimp on a good receiver, remember it’s the brain so get a smart one.

So now the car is sounding pretty good and it should be. However there is so much more that can be added to a car audio system. This is only the most basic of upgrades. For those that are serious about their system there are all sorts of fancy bells and whistles that can be added for increased listening pleasure and sound clarity. There are even mobile DVD players that can be installed for keeping the kids and teens entertained. The possibilities are and endless but for a quick increase in sound quality the place to start is with the receiver and speakers.

Once the brain is installed it’s time to move on to the speakers. For those that are completely clueless speakers are the things that actually project the music. The price range for speakers is huge because they come in all different shapes and sizes and there are endless levels of differing quality. For most basic upgrades a good two or three way speaker will work great. A two or three way speaker simply means that the woofer, tweeter, and midrange are all on the same speaker.
