Use a center punch to make an indentation in the metal to ensure that you drill the exact position for the screws. Note: Please use

The gauge of the power and ground wire is often an overlooked aspect of amplifier installation. The more power the amplifier receives, the more power it will produce. Power cables have a natural resistance, and will lose voltage by the time the power makes its way to the amplifier. The larger gauge (diameter) wire will hold more voltage over longer runs. Also, by having a larger diameter ground wire, the amplifier can run more efficiently. MTX recommends using a minimum of 4 gauge power and grou

standard for low pass crossover point is right around 90Hz. However, by experimenting with the crossover point (higher or lower) you will find what sounds best in this install. This amp uses a 24 decibel per octave roll off, which is pretty steep, or tapers off fairly quickly from the crossover point. This design complements both the subwoofer and the mid to provide greater musical detail. • Setting for Components and Separates: First enable the electronic crossover by selecting the “ON” pos
