You can fit 1” tweets in on the sails. It’s the same as my vw cc. I believe you also have 6.5” with same bolt pattern and molded speakers into the mounts as the vw cc. The upgraded Audi systems have 8” midbass. You can buy used dynaudio that are direct bolt in on eBay. And also Steg makes speakers molded into the moints just for vw audi
