Default need help with a class d home cinema

Hello, i am new to this forum and this is my first post.

So , here is my problem. I recently bought this LG subwoofer that i need to use without its headunit dvd. I have gotten hold of its service manual and have learned that it is a class D amp with pwm inputs. From the datasheets i understand this has some sort of dsp chips in it and has a digital interface with the dvd unit. I have built some analog amps and repaired some too but this digital creature is beating me up.
I need someone to help me make a connection from a spdif output to the subwoofer amplifier (and enable it) without the dvd unit that i don't have.

Thanks in advance.
