It ix wired for a sub woofer. Also the Alpine head unit required a direct battery hookup due to power use. At least that is what the Internets say.

I spoke (phone) with a Porsche shop in okc that is highly regarded.

I asked them what replacement head studs they use and they replied...Dilavar...

I was surprised. All my research says no, no, no.

Do I rule them out based on this or do I meet them face to face to hear their explanation?

If I dump these guys I will be on Tulsa time.
