Sound offs are not new to the World of car audio. In fact, they have existed since the early eighties and have continued as an annual event. Although this event started in California with probably only a number of fanatics, it has now expanded all over the world, since the evolvement of the manufacturers in the competitions.
Today, car audio manufacturers help shape the rules of the car 'sound off', as well as sponsor individual competitors. With the improvement of audio technologies, also came the focus in these competitions of sound improvement. For instance, with large subwoofers and powerful amps many car audio fans have competed for high quality sound as well as intense volume. Up until the 1990's, the chief focus was volume, but this changed around 1990 with the improvement of audio technologies and the nationalization of car audio competitions.
Although most competitions are very similar, there may be a different style of viewing the car audio system, depending on the type of competition and judges. For instance, you may drive through to a special booth for them to check out your gear, or they make walk around the grounds viewing each car individually.
You may also find specific differences between completion, depending if it's local, regional or global. Usually, the bigger the competition is (for instance global) the stricter the rules. Because the competition is much stronger, the rules are much more hard lined.
In the competition there are two main focuses, the installation quality and the sound quality. 'Sound offs' put much more emphasis on the sound quality, however, technical knowledge is still an important component to the competition. Besides this, a sound off competitor will be judged on frequency response and sound pressure levels. However, these are not as heavily weighted in the point casting system, as technical installation and sound quality.
Sound off competitions are often managed by car audio manufactures, who make the technologies used. Hence, it is expected that competitors use the newest technologies and the best out there, in turn creating the best audio system possible. It not only shows off some of the best audio systems and the competitors' technical knowledge and skills, but allows manufacturers to see what they can improve upon.

Car Amplifiers: for Clear and Consistent Sound
An amplifier is a device used for increasing the power and amplitude of a signal. The amplifiers are considered as modulating the output of the power supply. As a matter of fact, these devices take the power from a power supply and control the output to match the input signal shape, but mind it with larger amplitude. The car amplifiers as the name specifies determine the final audio output of your car stereo. It gives loud and clear sound on a consistent basis.
The connection structure is one of the important feature of a car amplifier. The selection of location for the amplifier is of an utmost important. One must always select the place that has a good air circulation. In fact, the airflow is a major consideration, as the electronics used in these amplifiers produce a lot of heat which can damage the components. The preferred place in a car for amplifiers could be in a trunk or under a seat, for instance.
Apart from this, it is always advisable that owner of the car must use cables with competitively larger diameters such as RCA cables. It helps the owner to connect the low level output of the radio or stereo to the low level input of the amplifieractory-installed receivers. This only comes with speaker-level inputs which requires special adaptors. Another important aspect to be taken care of is- the connection between the power antenna lead from the radio to the amplifier. It is always recommended that you connect the ground power cables before the RCA cables, as it helps to avoid damage.
Therefore, while installing an amplifier in a car one requires a power kit and RCA cables. A power kit contains the wiring that is needed to run power wires from the amplifier to the battery. The kit also includes a ground wire, fuse and fuse holder. This helps the users to add on additional car amplifiers in the future. On other hand, the RCA cables carry the sound signal from the amplifier to the radio. The RCA cable will run from the amplifier and connect to the RCA or pre-amp outputs on your radio.
While adding an amplifier in a car it is important to know about the speakers limitations. As a matter of fact, most factory speakers might not do well with an amplified signal, so must upgrade accordingly. One must look for the ratings of continuous power or RMS. These ratings will give the best indication about how much power the speakers can hold. Later on, the users must match this rating with the amplifier rating. It will ensure the users that they are getting everything out of the system.
The users must pay attention to ohms and power ratings. It should match accordingly. As a matter of fact, combining multiple speakers on one channel always affects the ohm rating of the system. It could be harmful if the system is not designed for it. Subwoofer amplifiers for instance, tend to be more forgiving due to their low impedance (ohms) ratings and flexibility.
To conclude, it can be said that while installing the amplifier in the car, one must make sure that amplifier gets enough air circulation to keep from overheating.

Amplifier car stereo help?
I have two kicker cvr 12" subs. They are 400 rms and 800w peak power individually. I was wondering what kind of amplifier do i need ( around what power). The subs are goign to be in two seperate boxes. I was looking at a sony 1200 watt amp and 250x2 at 2 ohms. i dont want the subs to be underpowerd by much but then again dont want to overpower them
You have two CVR's in diffrent boxes?
I would recommend putting them in one box, this will make the sub sound much more clear. Sony amp's are not so great. I would recommend staying with kicker and getting a 750. if you wire them up correctly in a single box, they will be 800 watts RMS, this amp will do 750 watts RMS therefor you will have the best power coming from your subs. I have them same set up, but i have my cvr's in the kicker vented box, which increases the bass.
