A subwoofer is a key tool to improve your car’s audio experience. This is because different cars have different acoustical landscape. The low-end bass is, for instance, the toughest frequency that can be reproduced by your car’s speaker.

The wavelength produced by a 20 Hz frequency, for example, is 56 feet. Your car’s small speakers may not have the capacity to reproduce such wavelengths. Adding a subwoofer is, therefore, the easiest and the fastest way to improve your car’s audio handling capacities.

Most car subwoofers have a diameter ranging from 8 inches and 15 inches. Ideally the larger the size of the subwoofer, the lower its frequency range. In most cases, however, the size doesn’t necessarily equate to accurate reproduction.

The most popular subwoofers on the market are the 10 inch and the 12 inch due to their capacity to reach the 20 Hz frequency level using relatively less power.

Getting the best cheap car subwoofer is not an easy task. Apart from cost, you also have to consider other factors like overall sound quality, construction material, power output, and inbuilt amplifier.
