I have a similar setup...see my previous posts and profile. I put the 6" 1990 enclosures in my 96 and the RCE 216 components set up as a coax in the rear. I didnt' know that bose grill even came off! That is great. I think I might un-coax my rears so to speak, and mount the tweeters there. How is the imaging with the rear fill there? Great sub and rear amp rack install BTW!
