You can get the pods from Italy no problem (aftermarket versions but same design as the original) https://www.ebay.it/itm/Supporti-ad...=item3afdcfdf1f:g:MJEAAOSwEW9aWiub:rk:14:pf:0
.. designed to take any standard 10cm/4" car speaker. If you're paying a chunk of postage anyway from Italy just do a search for "altoparlanti Panda" and you can buy pods bundled with a pair of suitable speakers - no end of choice.
