If your goal is to create the best sounding car stereo system as possible, there is one component that is absolutely crucial—the subwoofer. It doesn’t matter whether you listen to rock, rap, jazz or even classical, the addition of a good subwoofer will take the quality of your car’s audio landscape to the next level.
Many cars today feature head units that meet the standards of the Deutsches Institut für Normung (DIN). Put in place by German manufacturers, these standards outline the size and shape a head unit needs to conform to if it is to fit in a car hosting a DIN head unit.
Unless you like having stock speakers which are made with low-cost materials such as paper cones, purchasing aftermarket speakers will make your car investment that much more enjoyable. If you think about it, much of your commute time is spent listening to music, and aftermarket speakers provide considerable more quality than anything you will get from the car factory.
