Car Amplifiers: For clear and consistent sound

UK (SANEPR.com) July 8, 2008 -- 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.
