Step 1: You have to understand the speaker system Home theatre system comes with several cables which are usually connected to subwoofer or volume control. The connections include – one cable will connect the speaker and AC outlet. Power connector will be fed into subwoofer unit and wires from subwoofer will be connected to speaker and control unit. Cables usually come color-coded for easy installation and identification. Usually, green ones are for front inputs. Blue and black ones are for rear inputs. Center and subwoofer speakers come with orange or yellow cables. Make sure to match and connect the cables properly with corresponding ones. And also provide enough attention to the subwoofer connections. Step 2 : Know the PC Unit Most of the computer units come with at least 3 audio connectors. Green ones are for line out, blue for line in and pink for mic in. Computers that come with 6 channel audio with 2 additional connectors. 5.1 speaker system will require alternate plug-ins that function properly. You may have to use line in and mic in plugs. If the system has two extra outputs, then it can be drawback. This is even true if the 5.1configuration is already been used up. If the system can be connected and used, you may require alternate plug ins for functioning properly. You can use line in and mic in plugs but this can hinder the configuration. So, it is better to choose 5.1 model with motherboard unit. Step 3 : Installing Speaker PC  Installation process of speaker system usually depends on PC configuration.
