Choosing a dynamic and proper car adapter

How about finding the best car adapter?

The best car adapter is at your hands. Yet,Guest Posting try to become familiar with concepts and proceed accordingly. At times, your car stereo may be functioning wrong, and this must be addressed.

Car adapter and Power loss   

 Since the impedance is in series with the speaker, the amplifier is delivering power to both the speaker and the cable. Furthermore, the cable up the total system impedance, the amplifier will deliver less power. However, since decibels are calculated logarithmically, the cable must be very fine and very large car adapter length to the power loss is significant in terms of hearing, or in decibels.  Do not worry, this is not as hard as it appears. You will become familiar with each concept.

We could say that a loss of 1 dB is acceptable, and a reasonable loss of 3 dB, corresponding to waste in the cable 11% and 29% respectively of the power coming from the amplifier. Although the power loss is within reasonable limits, that does not mean that the damping is also reasonable. In fact, from the viewpoint of the damping factor, a reduction in sound pressure level greater than 0.3 dB is not acceptable.

However, for PA application / loudspeakers and sound environment in which the damping factor is not critical, we use a criterion for selection of wire based only on the level of pressure reduction (or loss of power). Moreover, the input impedance of a loudspeaker equipped with an input transformer typically ranges from several hundred to several thousand ohms, which means that the impedance of the cable is now small compared to the impedance of the speakers.

Car adapter Length and more

In practice this means that we can use a thinner cable (and cheaper), or carry long lengths of car adapter models. In these installations the only criterion when selecting the cable of power loss, forgetting the damping factor (since the transformer prevents the existence of a dry low).

Sometimes you decide to use speakers with transformers at a facility to avoid loss of energy, when often a thicker cable with low impedance speakers will give us a more economical system with power loss within reason.

What if your car model is old? Do not panic! If you have one that still uses tape reader, at any store we find a kind of audio cassette tape that allows a car adapter to connect your MP3. It costs a few dollars and requires no installation.
