I also have problems with the whining noise, so I have also bought the Stinger model.
How do I install the ground isolator?
It should be connected with rca-cables from the amplifier, but the rca-connectors are not used?
The amplifier was installed by a professional installer.
I have also Basslink II subwoofer and front system by Infinity installed by the same installer...
Any ideas how to do the installation?
Are is a link to the installation manual:
