Mazda 3 - Video tutorial

Model: Mazda 3 BK, MK 1 - Years 2003-2009
Part: Accessory Kit
Operation: Audio amplifier installation

A very important premise to keep in mind is that first of all the amplifiers, even if they use the same 12 volts of the battery, are equipped with a booster circuit. The function of the booster is to increase the voltage coming from the battery to a level that allows strong currents in the power amps.This task is carried out by a particular circuit called inverter which, in the best amplifiers, also acts as a voltage stabilizer. . The advantages of having a stabilized voltage as well as boosted are highlighted by listening, especially at high volumes and in demanding load conditions for the car battery. This premise lets us understand the importance of the power supply of the amplifier or in the choice of suitable cables. Once the installation position of the amplifier has been defined, it will therefore be necessary to set up the power supply system keeping these suggestions in mind: connect the positive to the battery with a suitable fuse protection, obviously choosing a section of the cable that depends on the power of the amplifier itself; the negative current cable must be connected to the car body in a point as close as possible to the amplifier, in order to minimize the length of the cable itself (remove the paint from the point where you will connect the negative cable which must be terminated with eyelet, avoiding to take the mass from the same screws that fix the amplifier).
