Would nakamichi with 50 watts per speaker also under power them?

50 watts per speaker would be fine

Is the 70 RMS watt rating per speaker or for the pair?

Each. 50 watts on a pioneer touch is under powering them.

What is the mounting depth?

If I remember correctly, was about 2 1/4" from the back side of the mounting bracket.
