Fx audio Xl 2.1 bl

[Stallion63]

Hi all!
I just bought the above 2.1 class D amp. Unfortunately I didn't notice that the subwoofer cut off frequency is set at 180hz. Is there any way I can mod the subwoofer
cut off freq to lower hz?

No one here knows? Or,is it not possible?
Appreciate any advice. Tks!
