Can you post the T/S parameters for the sub?

There is a C series and a Comp series. Does your subwoofer have any markings that say C12 or Comp12?

The Kicker recommendations for box size are for car audio use, in a house it is different. I will model this later today when I get home from work. Can you place the sub in a corner of the room?

18cm x 60cm x 65cm

Is this measurement the external size of the box?

 

[Mike P.]

That is hard to say as every room is different. It may not be the optimum place for the sub but it's better then having no sub at all.

49 liters ported tuned to 24 hz would require a 4 inch diameter port 31 inches long. Modeling shows the box is too small for this sub and low end extension suffers. You may as well put the sub in a 49 liter sealed box.

The usual connection is Kenwood LFE output - amplifier - subwoofer. I'm not sure if the SDPIF to Realtek will affect this or not. You will have to do some research.

 

[Mike P.]

Without knowing what the net volume of the box is and the tuning frequency, it's impossible to predict.

Hopefully the amp has a high pass filter around 25 hz to protect the sub from bottoming out.

how i can check this ?

It should say in the manual if the amp has a high pass filter and at what frequency.

Post some pics of your sub!

Nice! Let us know how it sounds when you get the MAC-AUDIO amp.
