Honda accord 8 horrible sound

Gwinambele

Anyone is using this unit on Honda accord 8 EU Premium Audio System with OEM amplifier?
Sound quality is horrible. Like there is to much bass and speakers are crackling. I've tried to play with all equalizer sliders but with no luck.
Maybe someone have same car and can give me some feedback. TIA.

Not the same car but a Honda Civic 9th Gen FK2 with a premium audio system aka external OEM amp.
I had hissing/humming issues so I got an Incartec hi to low converter (hardware equalizer and grounding insulator). It did the trick to decrease the over amplified audio signal being caused by the android radio amp on top of the
external amp.

I think the wires I got with Dudu is wrong in some way. I used wires I got from old android head unit I got and everything is working fine. Sound is loud and clear.
