[QUOTE="RGKeller, post: 8869392, member: 689826"] Hello all. New here and looking for advice on some issues I've been having with my JBL powered sub. I installed it about 2 years ago in my 2017 Ford Escape with the larger screen but non Sony system and it worked fine for several months but here recently it's been acting funny. I used the speaker level inputs to get signal and tapped into the speaker wires behind the factory head unit. Like I said all was good at first but here recently it's been getting quiet at times then will go back to normal operation. Sometimes it will do this back in forth several times during the same song and other times it will be longer periods before switching. I don't think it's ever shutting completely off or going into a protection mode or anything. It just gets quiet at times then all of a sudden gets louder again. I was told in a Ford Escape forum that the factory head units control module is actually sensing there is another speaker present and is cutting the ohms down to 2 to protect itself. Could this really be happening or is something else going on? Anybody else with a Ford run in to this issue? Any ideas or info would be much appreciated. Thanks all. [/QUOTE]
