A car stereo system doesn’t have to be expensive. If you have an older model car with an outdated stereo, you may decide you want to upgrade your audio system. The level of technological sophistication your car stereo has depends on what year your car was made and what make and model it is. Even if you are upgrading a 1980s system you can still find discount car stereos with modern features.

New cars will have state of the art CD changers and high quality audio speakers. Today’s stereos can accommodate Bluetooth technology so you can use your mobile phone through your speakers. You can talk hands free which is safer and more convenient.

In basic terms, a subwoofer is a speaker that is designed to reproduce low frequency bass. Some come with their own built in amplifiers, however some people decide to put together their own custom car audio system and choose each component separately. 15 inch car subwoofers are a popular size for many vehicle owners because they are not too big or too small and they provide incredible sound quality and the bass you want. There are other sizes available but for most the 15 inch is the most practical, affordable and useful.

There are many brands that make 15 inch car subwoofers such as Kicker and Alpine, for example. The price is going to vary depending on the manufacturer and features of the item. For around $84 Kicker has a Single Ohm subwoofer, this product is recommended for use with an amplifier which will drive up costs. As previously mentioned, some 15 inch car subwoofers come with the amplifier as part of the setup.
