Do you want to get the most out of your car’s audio system? Are you tired of all those stock speakers that sound like a tin can? If so, then it’s time for an upgrade. You might think that car audio installation Adelaide would require extensive knowledge about wiring and electrical components, but it doesn’t have to be that hard.

 By following these simple steps, any average driver can install their own sound system without having to go through the hassle of paying someone else to do it for them:

Disconnect the Battery

You should disconnect the negative terminal first, followed by the positive terminal. When you’re removing your battery, be careful not to touch any of its terminals with your hands as it can cause a shock and damage your vehicle’s electrical system. 

Instead, use an adjustable wrench or ratchet to loosen up each terminal before removing them from their respective posts. Once you’ve disconnected the battery, take some time to inspect it for any signs of corrosion or other damage that could mean trouble for your new car audio system in the future. 

These signs include discoloration around the posts where they attach to each other and around their corresponding terminals (which is usually caused by electrolysis), bubbles forming on top of each post (a result of shorting out), and bulging at either end (known as bulging).

After removing the trim pieces, you’ll need to remove the dash. This will reveal the stereo and allow you to access it. In many cases, this is a simple process of removing bolts and clips and pulling out the center console.


Disconnect All Wires and Antenna Lead

  • Disconnect all the wires and the antenna lead.
  • The power cable is located near your headlight assembly.
  • The speaker wires are located in the front doors, rear doors and trunk lid.
