Today my brother's VW Golf was fitted with his Empeg. The guy installing the unit didn't follow the manual to the letter.
He didn't fit the ignition noise filter. He said the car had one standard built in. Could be, because we don't get any ignition noise or wines.
He attached the grounded RCA's at the head unit's end. I pointed this out to him but he didn't understand my reasoning on the matter (I'm not an expert at this stuff). So I left it as is and told him I would testdrive the installation first.
Anyway we don't get any weird noises from the unit when playing MP3s. It's only when we use the radio, when we hear tiny 'clicks' when driving.
Tomorrow my Mustang gets fitted with my Empeg and I would like to avoid the 'clicks' from de radio. Does anyone know what's causing this?
