Re: Same old question, just need new points of view for new front stage
I would run two of the convertible CDT 2 Ohm sets so you can do a coaxial mount on one set and split up the other set if you prefer a separate tweeter. Putting tweeters on the A-pillars does help raise the sound stage but it introduces a lot of reflections off the glass at the same time. I'm not sure what you meant by listing all those power numbers but I would go with 200 Watts at 4 Ohms for 2 sets of 6.5s.
