Basic amplifier wiring diagrams are subwoofer voice coil, impedance, amplifier connection, bridging an amplifier and wire gauge. Impedance is the total electricity opposition collected in the subwoofer against the output of the amplifier.
It is easier to wire a single coil subwoofer because it is difficult to calculate the impedance. Voice coils have single and double features, and the single have two terminal posts, while the double has four terminal posts. However, bridging the amplifier is when the individual merges the channels of two amplifiers, resulting in one channel. Therefore, experts advise that individuals use a 12- to 14-wire gauge to connect the subwoofer.
