Russoun MCA88

Hi ,
Is there a way for a non certified installer to reprogram a MCA88/amp?
I built a copy of LX mini speakers and got this amp from a demo :could be OK to use until my chip amp is finished. The only problem I have is the controller is coming from an existing system and was programmed for it.

My setup is a source going into MiniDSP and then into amp. I'm using an Audio Source 100 amp now, powering two speakers and the 6in woofer barely works (it is rated at 4Ohms), with significant noise /buzz.



Te Russound has enough channels for me, if I could only unlock and use them without Keypad.


Thanks
