Kippy,
I just made an adapter for my car for an SC811... it costed me about 10 bucks all together... All you need is:

1) a 6 pin DIN, you can find this at a bunch of different specialty electronics components stores (radio Shack won't have it). $2

2) 4 female RCA plugs. (to adapt) 6$

3) 1 12-16 gauge wire from ANY device. (For the signal relay) hopefully free $1

4) Soldering gun and solder. hopefully free or $5


I will send you the schematics of the 6 pin DIN if you leave an email address. I personally used the adapter to hook up a few amps and aftermarket speakers to the int. of my car. The DIN in the back of the head unit is originally made for the VOLVO amp for the SC811 which is OUTRAGEOUSLY expensive for what it is.

The DIN in the back of the head unit is basically a low-level output. Theoretically, the interior speakers will be disabled once the DIN is hooked up, but in my case this wasn't the case.

Good luck!!

P.S. Just so you know, this may sound complicated, but I am a complete IDIOT when it comes to electronics. If I could do it, you can do it. I will help you in any way possible.. Just let me know.
