I bought my macan this week. The dealer in Houston had three, all loaded, but with Burmeister stereos, and were waiting on the amplifie. They couldnt sell them, since they could loose their license from Porshe. Apoke to the manager about this, and I too was willing to sign something saying you owe me this amp, and to have it installed in a month or so, but no go. manager also cited safety issues (not sure how an amp impacts safety). Apparently, he has 10 cars (all models) on his lot that cant be sold due to these Burmeister amps.
I bought one with Bose instead
Hope Porsche had delivery and performance guarantees as part of their contract!
