1, car amplifiers have fission and integration (common) subwoofer, 2, 4, 6 road speaker output, etc.
2, connection method: there are three power supply, + 12 v (large motor + 24 v), the control side (REM), earth (GROUND) or by iron, + 12 v termination battery positive electrode, control (REM) is also a + 12 v, is to launch a car later on, to power amplifier a turn-on voltage, power amplifier can work, because of the power amplifier power consumption big, stop not to give it to work. The loudspeaker connection and signal input is routinely. Some more than with plastic plug plug, must points clear connection position.
3, subwoofer connection power, passive subwoofer can use fission power amplifier bass tong bridge connection method, two horn line tap around a track + side, to increase the output power. - end is interlinked, there is no answer.
