I have a problem with Ignition noise (I think?) I hear it mostly when the player is in pause or
playing with low volume. Anyway the engines revolution speed sounds in the speakers.

I do have mounted the filter on the empeg +leed

+BAT-FUSE---FILTER----EMPEG
-BAT-----------------EMPEG

And I have also mounted the audio ground leeds in the AMP end of the audio cable.
(I have also tried without the audio ground leeds, but no changes).
The audio ground leeds is connected to the car bodywork.

1: Audio leeds (5 meter / 200 Inch.)
2: Audio ground leeds

EMPEG--1----------------------------12--2-AMP

The AMP is mounted in the trunk.
The AMP is supplied with an 7G wire straight from the battery, but not filtered.
