Just a quick follow up. I had the Alpine R2-s69c (dash and front doors) and the Alpine R2-S69 (rear doors) installed in my truck today. They are playing off the stock Alpine amp in my truck. They sound absolutely incredible!! I cant believe how impressive the soundstage is. 20 is the loudest that I went. The bass was shaking, no distortion. Theres no need (for me) to go any louder than that. Even though they are 85RMS speakers, the 50 watts per channel is plenty!
The rears are coaxial, and the FILL the back seat with sound, and spill into the front a little bit. Its like being completely surrounded.
I was planning on doing a second stage with an Optim8 amp and sub. The guys at the car audio place told me they didnt think that I needed the new amp. I totally agree. They basically kissed $1,700 goodbye by making that recommendation.
If you are in the Houston area, Bico Stereo is the place to go. They did my last Ram also.
All in, it was $750 and worth every penny
PS. I didnt use an ANC bypass harness, and there is no interference at all in the sound. Not sure if its because everything was Alpine
