Nowadays, you can buy cheap car CD players with front 3.5mm auxiliary inputs. This allows you to directly connect your portable audio player, such as an MP3 player that has 100s, if not 1000s of songs stored on it.

There are also other features that car CD players have that will increase your options when listening to music. They include, "Satellite Radio Ready", HD radio tuners, SD memory card slots, USB inputs and more.

Car Speakers
Car speakers are another outstanding component in a car audio system. Replacing your original speakers with aftermarket car speakers will present you the opportunity to unleash all the detail in your music, including all highs and mids throughout the frequency range. A lot of these frequencies might not be reproduced through the speakers you have already, ultimately leaving you with "Lack of Detail in Sound". This is important because you really want to hear 100% of what is being played. Not only do you want the singers voice to be clear and vibrant, but details from cymbols crashing on the drums and other musical instruments and effects should also be heard in full detail. Upgrading your cheap car speakers will allow you to acheive high quality music.

Car Subwoofers
Car subwoofers are needed if you desire to have decent bass levels. Even if you had 6 1/2", 100 watt RMS speakers in the front and the rear, your bass output might not be that significant. You could also distort other frequencies if you try to gain too much bass from your speakers. Adding a car subwoofer or a pair of cheap car subwoofers will generate enough bass for anyone to enjoy. The most common size car subwoofers are 10", 12" and 15". If there's enough room, many people decide to have a pair of subwoofers. But if you're not looking for an "extreme" amount of bass and simply trying to add some that wasn't there before, or there's a lack of space, having one car subwoofer will easily do the job.

Car Amplifiers
If you want your volume levels to soar high in the sky, you need a system with a good amount of watts. Your car CD player will most likely not supply enough power to allow your upgraded speakers to sound their best and will never be used to power your subwoofers. This is where cheap car amplifiers come into play. They take the audio signal and amplify it many times over. Depending on how many car speakers and car subwoofers you have or are planning on using, depends on how many channels your car amplifier(s) need to have. The most commonly used cheap car amplifiers are mono class D (1-channel), 2-channel and 4-channel.

With all of these car audio components in place and installed, you'll hear how amazing your music should have sounded a long time ago.
