This is actually what my friend and I did, I'm sure there might probably be better / more efficient ways (less wires) to complete them.
Here's what we used
Two MITAH adapters
The stock 6-pin DIN cable (male/male)
Another male/male 6-pin DIN cable
RCA Y-adapters
http://www.installer.com/hilo/Coming from the AMP, it goes:
6-pin DIN cable ---> MITAH adapter ---> 4 RCA Y-adapters
Coming from the HU:
6-pin DIN cable ---> MITAH adapter ---> Connect to RCA Y-adapters accordingly
After that, you're left with 4 open RCA plugs from the Y adapters:
Front right, Front left, Rear right, Rear left
with two more Y-adapters connect the Front right + Rear right, and then Front left to Rear left.
Hope this can help ;)
Connect those two RCA plugs to an RCA-to-mini plug adapter. And then of course the mini-plug connects to anything you it to. Connect the blue remote wires together. We also made a on/off switch to eliminate the static coming from the aux port when no music is being played.
