Mk4 Subwoofer And Spare Wheel; Possible?

[ric01]

Hi all,

My newly acquired 2011 mk4 estate has the ford stereo upgrade with the
subwoofer in a polystyrene 'housing' in the boot where the spare wheel
goes. There's no spare wheel, just a puncture repair kit.

I want to put in a mini spare wheel with jack and keep the
subwoofer. Is there room or will I need to relocate the subwoofer?
And if so where to?

Pic attached to show what i have now (not my car but the same).

Thanks
