The 2022 new Mondeo alert tone becomes sharper.

Generally, the resistance is added on the basis of the original CD, with DSP or power amplifier and prompt tone (reversing radar, opening the door, fuel quantity? Foot, seat belt) sharpened. This solution is to connect four 25-watt and 4-ohm resistors in parallel between the CD player and the DSP or between the CD player and the power amplifier (the input terminals of the four speakers of the DSP and the input terminals of the four speakers of the power amplifier) (each group of wires of the four speakers is connected in parallel with one resistor).
