I have a 2017 FFH it has SYNC and the 4” Radio with standard sound system no rear deck speakers and I don’t believe there is a stock amp. I have installed a LOC, Sub and Mono Amp successfully. My only issue is that when turning up the volume it sounds like the level of the sub is reduced the higher the volume. I have read many posts about the ANC but not sure if that is what is reducing the level of the sub. Wanted to check and verify if that is what the ANC is affecting, I do not have a buzzing or feedback that some of these posts mention from the ANC. Any help/feedback would be greatly appreciated. This is my first FF and my first Hybrid vehicle so it is all new to me.
my install went like this.
FL+ = White
FL- = White/Brown Stripe
FR + = White/Violet Stripe
FR- = White/Orange Stripe
Remote Turn On = Brown/Yellow Stripe
P.S. I am loving this vehicle and the gas mileage
