CN10-03304B external amp Subwoofer setup question

[jordanh]

Hello,

I do not really have any troubles but just a setup question. Today i got this huge Subwoofer along with this amplifier. https://www.esxaudio.de/english/assets/se3500d.pdf
Sure i connected the external amp to the corresponding output of the radio which enables me to control the bass power using the equalizer app - bass lever.

But i have troubles finding the right setup for bass quality. I assume my problems araise from the fact that the amp requires to set the low-pass frequency BUT at the same time, the Head unit already comes with a low-pass filtered signal anyway.

So the question is, at what frequency is the built-in low-pass filter running and does the value probably change when playing with the equalizer app-bass lever? What would you recommend to set on my amp - set the highest low-pass filter possible in order to play the full signal from the head unit?

Thanks!
Harald

Hi, the frequency of the built-in low-pass filter is 20Hz -100Hz.That means frequency of the original signal must among 20H - 100Hz that can be output .
The value will change when playing with the equalizer app-bass lever.
