I'm sure that this has come up before, but I've searched and can't find the relevant thread.

Does anyone know of any car amplifiers that have digital inputs? I've searched the web and can't find anyone making them. It strikes me as odd that the car audio market has not embraced digital interconnects given the serious difficulties encountered with ground loops and interference when using remotely mounted amplifiers.

I'd certainly be looking at getting an S/PDIF output board for my empeg if I could only find a suitable amp.
