I have the new type s in my car running on a 4 channell amp and it sound good. Better than any sound i have heard. I have the exact same set up you are asking for. Type r are the better way out, but if you have a small mounting dept, the car will have a little rattle. The sound quality is a little bad compare to the type s. I have tried both. The type s produce better frequences but less bass than the type r. Go with the type s.
