Audio Wiring / September 4, 2018 / Ally Saldivar.
Remove the head unit from the dash. You’ll be connecting not only the RCA but also the remote turn on lead. Connect the remote turn on and run it alongside the power wire on the driver’s side all the way into the trunk. Replace the driver’s side carpet and panel. The RCA cables should run down the passenger side.
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.
Perhaps the most time-consuming and most important element of a car audio installation is the wiring. There are power cables, ground cables, signal (RCA) cables, speaker wire and more. Then there is the connection of cables to ignition sources, constant 12-volt sources, etc. The process may sound overwhelming. However, if you attack it in small bites, you will find that it is not as difficult as you expect.
To understand the function of the car audio crossover one must first review the role of the car power amplifier. The power going into the amplifier comes from the car battery. After passing through the amplifier, a stronger and more powerful signal then passes into the car’s speaker system.
