A subwoofer is the part of the audio speaker system in a home or auto system that reproduces the bass frequencies. A cone subwoofer will reproduce the bass tones from about 20 HZ down to 200 HZ, the point where the sound is as much vibration as tone.

Typically drivers found in movie theaters, concerts, radio stations and live records in the 15 to 18 inch range. A auto stereo system which comes from the factory usually does not include car audio subwoofers, aficionados of the hottest systems find they need to add aftermarket car stereo subwoofers.



INSTALLING CAR AUDIO SUBWOOFERS

It is common for subwoofers to be installed in the trunk of the car, since better sound quality is gained by separating the car subwoofers from the balance of the stereo system. The process for installing car stereo subwoofers is somewhat complicated, so it is recommended that you buy the subwoofer enclosures prefab.

Apply sound deadening material such as Dynamat or Accumat to glue coated and cleaned metal of the trunk floor. Now it's time to place the subwoofer enclosure itself. Following the instructions for the amplifier, wire the car subwoofers into the two rear audio rear speakers.

The subwoofer boxes can face the front or rear of the automobile with different sounding results. Once you have made the decision as to where the subwoofer enclosure will be place, drill and mount the brackets in the correct place to hold the subwoofer box firmly in place.

HEARING LOSS
Some car audio subwoofers seem to be in competition to produce sound pressure levels that are dangerous to one's hearing, especially in the confines of the automobile. These cars with their sound pressure levels in the red-line area of permanent hearing loss are not able to produce good sound quality, but the quality is less important than sound pressure.

To enhance the vibratory effect of the stereo system, a new devices called subwoofer boxes which transmit vibrations when attached to furniture. These subwoofer enclosures provide the feel of the big subwoofers without attendant hearing loss.

Car owners and manufactures often add the car subwoofers with the car audio system to enhance their performance and to take them to a new level or sound excellence. In fact the subwoofers are complete loudspeakers that are dedicated to reproducing bass audio frequencies. The frequencies range from 150Hz to as low as 20Hz depending on the taste and requirements of the user. 

Main designs are bass reflex, horn-loaded, band pass, and infinite battle types.
Broadly the subwoofers can be classified into two types. Passive subwoofers consist of the subwoofer driver. On the other hand the active subwoofers have an inbuilt amplifier in the subwoofer. 

Numerous qualitative subwoofers that are used for the car audio and stereos are available in the market today. Recently the Infinity Systems, one of the units of Harman International Industries announced their new line of subwoofers. 

Today the subwoofers use large-roll surrounds, polypropylene cones as well as progressive spiders in them. In result they have gained optimal control of the sound system and made the bash sound effects free from distortions and also prevents sound from breaking down while delivered. In result the subwoofer gains much greater durability. Large roll surroundings help the cone edge maximum suspension eliminating any rattling that travels up the edge.
