I recently got a 2014 xf and it just has the base audio system. I think I have found the trunk sub plug but tested for voltage on each pin but got nothing. I also notice I have to turn volume level up way more then the 2013 I had which had the Meridian audio. Can I get a Meridian amp and replace my base one for better sound? Could I then also get the trunk sub and plug it in to the Meridian amp and it power it?
