Hello. In a topic in another forum I have read that you have to use a high-low adapter in factory radios where you want to operate a power amplifier with subwoofer if the power amplifier has such a function. I have also understood that so far. Furthermore it is told that you have to take the signal for the high-low converter from the speakers. I also understood that. But why do the speakers have to be disconnected from the signal for the high-low converter? the converter is taken? In the topic it is also mentioned that you better take the rear speakers for the converter, but why just clamp off completely? Turn off is also possible?! why should this be so bad. I can understand that many want to keep the rear speakers in operation because it actually disturbs passengers when they hear only the bass trumpet at the back but not the medium and high frequencies. how much should the sound image be negatively influenced when the rear boxes It is also written that at the Sony CD Radio (Ford Mondeo MK3 Facelift) at the rear of the FAKRA? Plugs are two pin assignments for the Sub+ and Sub-. can I go from this pin assignment into the high-low converter around the power stage and finally the subwoofer operate? and if so, can the rear speakers remain clamped on and continue to use? Does the 6000 CD Radio (Ford Mondeo MK3) not also have such a plug with the same P IN Occupancy? after all, these have been installed in the same models and should therefore all have the same cable harness and connector or? As you can see, ask about questions, I hope someone can answer me if my reading was not too tiring to read and I was understood. Greeting Florian
