Door cards with speakers

[Zibodo]

I have a 98 base model that only came with dash speakers. Someone previously installed door speakers by cutting a hole in the flat door card, but they sound very tinny. I would like to upgrade to add better door speakers but still keep things original. I have a set of HAES speakers in housings that I can modify and I have been trying to locate the proper door cards on Ebay, but am not sure I am looking for the right part. My interior is savanna beige vinyl and carpet and when I look at the Porsche parts catalog I find lots of different part numbers for that color, but no indication which ones have the speaker provisions and will fit my 98. Can anyone help identify the proper Porsche part number?

Thanks
