VOLVO XC60 Subwoofer Install - AFTER

I have the original Sound System from VOLVO. No Harman Kardon or B&W Soundsystem.

Now i will install a VOLVO Subwoofer (See Photo) Part Nr.: 32212620

Now my Question do you know witch side in the back i install the Subwoofer. This is normally the original Subwoofer.

Is it possible to install that normally?

I do the side wall away and than i will install the subwoofer on the original position.

I hope u can help me guys!

Thanks
