A car amplifier is needed to raise the audio input level. The sound quality of your speaker system depends on the correct choice of this equipment.
Instructions
Step 1
When choosing an amplifier, pay attention to the build quality of the device. Examine the case carefully for cracks, poor connections and many other small things. The physical size and weight are the conventional indicators of the power output of these devices. It is believed that the heavier the amplifier, the better its performance. However, now the industry produces devices that have a thin body and have excellent parameters.
Step 2
Pay attention to the sound class to which this amplifier belongs. For class A-B devices, an important indicator of the output power is the allowable current of the supply fuse. Remember that this type of equipment is characterized by a large enclosure size and increased heat emission.
Step 3
Class D are digital audio power amplifiers. For them, the size and value of the current do not actually matter. For this type, the main selection criterion is cost, so here look mainly at the state of your budget. If you are looking for a cheap digital amplifier option, then take a look at manufacturers such as Power Acoustik and Boschmann. They produce amplifiers that are virtually on par with their more expensive counterparts.
Step 4
Remember that the car amplifier must have a power that is 10-20% less than the power of the speakers installed in the car. Otherwise, there is a high risk of getting a mismatch between the two units, which can lead to failure of the speakers.
Step 5
Do not forget to check the quality of the connecting wires and the thickness of the power cable. Be sure to select the parameters of the wires taking into account the characteristics of your amplifier. To do this, you must know the power, which is indicated in the technical documentation of the speaker system and the number of RCA outputs from the radio.
