So I have a 2000 c70 with the dolby suround sound sc901 stereo system sounds awsome but I would like to put my pioneer avh-p4100 in. I know I will lose my center channel speaker but would like to keep the factory amp running dose any one know where I can find a amp interface in the us have sceen them in the uk Autoleads PC9-414 but are hard to get here. Also since the double din is slightly larger do they make a trim peace to correct or do I just have to make one my self any help would be great thank you.

 

I found this and it might be what your looking for. The description says V70, but in the details for the harness it says it will work with the sc901.
