I can relate to this.. and If necessary I will name, names as pertaining to those who "claim" that our Wraparound didn't need any sort of support (speaker bar cover) attaching to our 08 wrangler. However over the last 2 1/2 years we've been running the Bestop combo as supplied to us by Morris4x4 The bikini, wraparound jammer & duster. But things didn't start off as easily as one would hope and over time.. the cinch straps (made from a cotton poly blend) have torn away in two places over the speaker bar.
The thing I wanted to point out.. is that we who buy many of these products need to either send them back directly right after a problem has been discovered or take it upon ourselves to make the necessary alterations in order to make these thing fit/work.. I've accepted the challenge of making these things work.. and because I can sew but I'm not a seamstress.. I will do more than a few alterations to my current setup.
As for the soft door.. yes, We've been running this in conjunction with the Bikini, jammer and duster.. leaks have developed around the surrounds, but a homemade weather stripping has correct this.. for now. But upon first installing the soft doors.. things just didn't line up correctly.. Calling Bestop, the spokesman simply told me to "force it". I didn't agree with his attitude.. but did as he suggested.. it doesn't take a rocket scientist to figure these things out and when one deals with a slight margin of error when working with fabric, things simply do not flow or align easily onto the jeep.
So.. Yes the soft door will work with the biniki/jammer/duster combo.. but it will take a bit of getting use to because often the doors will flap towards the top when the jeep enters into a high wind area. I recall crossing the bridge into Outer Banks over the weekend and there was a wind warning.. We both held the doors until we reached the other side.
As for the image above as posted by the Oper.. clearly one can see the opposing channels.. in this instance I may have been upset also.. but I believe a few snips and restrict would have corrected this or at least that is what I would have done.
