Ya I didn’t think there was a need really but the guy at plug n play insisted newer fords needed one because at times the radio may not send signal because it doesn’t detect the aftermarket audio. The kicker key 200.4 has the resistors built in where as the key 500.1 does not.No, that’s the beauty of the kicker 500.1, it can handle factory amp signals as high level inputs. Basically has a built in LOC.
im just trying to think of a reason his doesn’t sound right. When I had my sub hooked up before I added the 200.4 i didn’t have any issues. But I added the resistor later just because plug n play was so adamant about it.
