Nearly everyone who has sat in traffic has noticed the mind numbing amounts of bass produced by some car stereos. What most drivers aren't aware of is how to buy a system of sub-woofers for their own car. The most noticeable feature of these systems is their price which is limited only by human imagination. The most basic understanding of how much these systems cost, although varied by complexity and brand name, lies within the power of the components that comprise them.
The power of a system is measured in watts. The more powerful the system, the more watts of electricity it is capable of receiving and transforming into auditory noise. Speakers designed for bass, or [sub-]woofers, range in power levels from 50 watts which can hit 65 to 70 decibels, approximately as loud as traffic on a busy street. These smaller woofers, generally the 10 inch or 12 inch variety, usually cost between $30 to $100 each. The largest woofers can handle several thousand watts reaching over 150 decibels loud, as loud as a rocket engine.

A a low wattage amplifier that lacks tonal quality can be purchased for as low as $150 each. High power amplifiers with the purest tonal quality would start at $450 and go up from there. How many amplifiers will be needed to properly power the woofers depends entirely upon how many woofers are chosen to be installed into the mobile entertainment system.
The final ingredient in completing a car stereo is to pick which type of enclosure to install the woofers in. These boxes are made of wood and are carpeted, generally costing around $150 to $250 for the basic setup. There are no major differences in cost, yet there are three major types of enclosures to choose from. The first is a sealed box designed to allow
