- First of all, pull out all the built-in speakers from the car. In that case, use the T20/T15 screwdriver along with the head driver.
- Remove every nut from the hinges so that the speaker completely comes out
- Make sure to unplug the wirings from the electric board. Try the unplug the wires with steady hands
- Disconnect all the clips of series
All the speakers are removed. Now it is time to adjust to the new one.
Installing the speaker:
- Put the speaker and midrange in their accurate places. Don’t forget to use measurement tape just before the attachment. It will help to assure the sizing and space of the compartment.
- As the principal speaker is done connecting, plug in the woofer and tweeters in different areas
- Use the screwdrivers to adjust the speakers with the dashboard and body successfully
- As the door-sided places are complicated, they can be removed from the entire body and get wired up.
These are the ways of installing the speaker with the tweeter. Follow a similar way of installation for both the amplifier and the woofer.
By maintaining the sequence, the speakers can be changed very easily and perfectly.
