Common Problems
Still no sound
Sometimes it is necessary to remove battery and let the system boot up together. Also check that the remote trigger wire is providing the 12v supply required to operate the amp. Also check the 30 A fuse in the drivers side fusebox –
Double check the plugs are both fully inserted – especially the small one
Also , we are finding that the ignition switch can fail – this stops the power being supplied to the amp.
No sound from drivers door
Very often the speakers can also be damaged when the amplifier goes faulty , it may be necessary to remove the door card and inspect the speaker plug/loom , they can suffer from water ingress as well .
The speaker cones can also be damaged when the amplifier fails – they should read around 6 ohms impedence.
Battery drain
Check the switched ignition feed switches between 12v and 0v with ignition switch.
