  1. Draft a blueprint. The first step to installing new audio is for persons to design a plan that will keep them guided throughout the entire process of the project. In this plan, persons should design a workspace for the building/construction of the new audio system as well as a second workspace that is able to fit a car. Persons will need to install the audio system using the second workspace after it has been constructed in the first work space.
  2. One’s workspace will need a bench for each workspace as well as filing cabinets slat-boards or pegboards to layout and place tools. Persons should also be mindful of the need to install new electrical outlets using a brand compatible 20 amp breaker. The extra electrical outlets will help to power tools along with the fluorescent light rack and the 24” drum fan and other devices and tools needing electrical charge. The respective parts of the audio system itself – such as the In dash CD Player, CD Changer, Amplifier, Subwoofer and Speakers should all be easily accessible and have its own space.
  3. After gathering all the tools and setting up the workspace, persons can go ahead and begin to assemble the audio system. The audio system is to be constructed in parts and then assembled and installed. It works as such.
    • First, persons should design and construct the square enclosures for the speakers and subwoofer.
    • Install the amplifier by mounting the amplifier board (also known as the amp rack) in the respective locations.
    • Next, persons should remove the factory sound system. This is the sound system that comes as a part of the car. To remove the factory system with minimal damage, persons should remove the dash trim, door panels and factory door speakers.
    • After removing the factory sound system, the new speakers are ready to be installed. Not the type of connectors that are to be used for the speakers and for passive crossovers. Ensure also that subwoofers do no overpower and subsequently damage speakers.
    • Secure the head unit by carefully connecting wires to the new head unit and sliding it into the dash for a flash fit.


  • Workspaces should be large enough to accommodate the scope of the project.
  • The distance between the two workspaces should be minimal as one will be required to move back and forth between the two spaces.
  • Persons should be careful when setting up electrical outlets and connecting wires as there is always risk of injury and harm.
