Audio setup - help

[DeeTurbo]

You need an amp to power the sub and the amp will need a power cable running to it from the battery. It will also need to connect to the back of the headunit to get a audio source from the sub output rca.

Just thought you might want to check the polarity is the right way on the speakers.

The way to check if the polarity is correct is: 

• use the fader to bring the sound to the front.
  
• use the balance to shift the sound to one side.
  
• listen to the bass
  
• move the balance to the centre
  

Now if the bass sounds louder the speakers are in phase and connected right but if the bass goes quieter the speaker will be going out of phase and that means there not connected right.
