Hold a phone folks! I have your solution!
I've been working with Julian from m0bridge on the diyma forums.

"We do now have a complete DSP MOST25 1KW amplifier now available. It is a BMW version of our OEM manufactured unit developed for an OEM. It comes in an 8.1.1 (there's an extra preout for adding an additional sub amp) configuration. The unit comes with a 300W RMS sub channel, 2x120w RMS high powered channels and 6x75W RMS. We'll be listing the complete details on the amp in the coming days on our website."
They have about 100 of these things to get rid of. I am going to get one from him. To facilitate, mention my username and message m0bridge on diyma forums.
PM me if any questions. I think they are pricing these at 1k. Considering the cost of a DSP, dmi, and 1kw amp, that is a killer price!
