I have a 2012 Grand Cherokee Overland Diesel.
Now on Saturday I installed a Line output converter behind the head unit which was tapped into the front speaker wires...
now the problem is everything works fine except I have NO VOLUME control on the subwoofer like it does not sync with the HEAD UNIT volume ??
But when I control the volume on my IPHONE the sub volume follows the volume on the head unit if that works why does it not just work normally through the head unit as it should?
also I have done my research on the forums and read everything about installing a LOC as to connecting it after the amplifier I also did that and sound is very crap
as for the PAC adapter I don't really like to use them as on my last car it basically popped and almost caught on fire lol..
Thanks to everyone.
