Alpine 9855r Performance

Hi everyone. .

Today I installed my new one 9855r and I have this issue..

If I don t use any kind of eq, I can increase volume until distortion that happen at around 28/35.

At 26-7/35 I have loud volume with great pressure..

Instead, if I use factory or user's eq after 23-24/35, the volume stop to increase and remains at same level even if with rotary I go to 30 or 31..

In this second case, I have clean sound, but is not enough loud and have not enough pressure

Could you kindly help with understanding and or solving this. .?

Thank s in advance[emoji6]
