Audio Wiring / September 5, 2018 / Bristol London.
Begin connecting components using 18-gauge or 16-gauge wire on the speakers. The cables run from each speaker to the amplifier. The longer the run, the more resistance on the fence. The larger the gauge size of the cable, the less strength.
After connecting the speakers, run the wires to the amplifier and connect the positive wires to the positive inputs of the amplifier and the negative wires to the negative inputs of the amplifier. When wiring speakers together and to the amplifier, you need to consider the impedance, or ohms, a rating of the speakers as well as the ohms load of the amplifier. Amplifiers are constructed to “see” a specific ohms load. If the amount the amp sees falls below what it is capable of handling, the amp will shut off.
Today one gets the sense that all types of communication have chosen to convert to a digital system. Some digital equipment may have made its way into the sound system of the average automobile, but most the present-day cars still use an analog sound system. The requirements of an analog system dictate the construction of the audio power amplifier and the audio preamplifier.
There are manuals sold for easy car amplifier installation. However, following some easy steps will ensure proper installation. First, is to fit a wire that goes from the car’s battery to the trunk where the amplifier will be placed. The cable will need to go from the passenger side, under the carpeting, and under the seats. The car’s instruction manual will show how to remove the seats to get the wire underneath. Once this wire is in place, the car amplifier can be connected. It is effortless but can take some time to run the wire through the car. Seat removal can take some time
