Are these cars prone to the sunroof drain issues that the allroads were? I'm going on my second amp as it's crackling in two speakers now, right rear and left front. 1st time is was speaker replacement (no sound) then amp replacement, per autosound dealer. I sourced the amp on ebay and it was pristine upon installation. Just wondering as I consider my options, which will not encompass the full mcintosh, focal, etc. Have pretty good pioneer avic professionally installed by PO, so would rather not redo everything.
