Audio Wiring / September 9, 2018 / Skyler Liang.
Gather the following tools: knife or wire cutters, solder, and solder gun, crimps, stripper, screwdriver, screws. Plan the installation. Know where you intend to put all the components. For example, the radio commonly placed in the factory opening in the dash, the speakers are put in the factory openings in the front doors, and the rear speakers put in the factory openings on the back deck. The equalizer goes in the factory opening below the radio in the dash. An amplifier with built-in electronic crossover usually goes in the trunk. The car’s battery, which powers the system, is commonly under the hood, usually on the passenger’s side of the vehicle.
When a car owner plans to purchase a car amp, then that car owner must give thought to the amplifiers desired efficiency. The effectiveness of an amplifier represents the rate of power output into power input. Two primary factors determine an amplifier’s effectiveness: the power dissipation within the car amp and the distortion of the audio signal that comes from that same amplifier.
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.
Use a self-tapping sheet metal screw and drill through the metal on the backside of the seat or into a part of the trunk floor NOT IN CONTACT with the gas tank. Remove the screw, and grind off any paint around this area. You want a conductive connection to the chassis. Drill the screw back into the hole you created, this time with the ground wire attached. Use some silicone sealant to seal up the bare paint area to prevent rust.
