Hi there,

I just transferred match sound system from 2017 c300 to 2020 glc300. After installation, everythings working fine but woofer is sounding very weak. I checked connections and everything seemed fine.

Does anybody know if new generation headunits have factory crossover? Because match amplifier getting signals from headunit and transmitting to woofer with subwoofer out. I am guessing because of factory crossover maybe door speakers not getting low frequencies (lets say below 150 hz) so amplifier doesnt send below 150hz to woofer and sounds weak.

any ideas??

I fixed it myself.

i used FL and FR output from headunit to amplifier FL and FR Input.

for woofer, I used bass output which is purple color from another socket behind unit to RL input of amplifier.

with dsp tool, I set input output routings like in picture. Now everythings working fine.
