You have to rewire the entire system, but it is possible.

 

I guess I would lose my factory PCM II then, no?

 

I would recommend that anyone thinking of an upgrade to their audio or video system give Rick @ Reus a call. He and his staff are the best and know their stuff (our cars). His installer arrived today at my house at 9am and spent the entire day here. He left at 6PM and was in no rush to leave.

It was a pleasure watching a true professional take apart my car (and he did), answer my "basic" questions along the way and put it back together. They know what they are doing (they done so many conversions) and I could feel the confidence throughout the installation.

I've had other aftermarket systems put in my C-2's and C4S (Xtant, JL Audio, MB Quart, etc.) and I can only tell you that I was concerned watching the local "young" installer cut and tape wires he was only looking at for the first time in my P-car.

I hope this helps anyone contemplating an upgrade. I'm off to the garage to listen to the system again.....
