I'll leave mine till they go south, and I suppose I'll find out after I hook this amp up tomorrow. That is the firm deadline for it, and I'll post my final setup and results tomorrow evening. If I do kill them though it is good to know there is an attractive alternative out there. Though powering them will once again become a concern.
I suppose if I somehow kill the speakers, but not them amp then I'll just cough up the dough for new speakers and custom made adapters for them to mount to. I'd rather not spend the cash on it. The car has 175k miles and I'll likely add a newer E class to my driveway to replace it when I get out of Uni this semester. I plan on always having this car though as it represents my first love for the "three stars" Plus everything about the car is solid as a rock (Bose amp not withstanding) so I might even drive it for a few more years before adding another one to the herd.
