OK! I'm returning the rear RF speakers and getting MB Quarts for the back (coax, I know, I know, but these will remain stealth). They're going to do the icky work of getting the tweeters and crossovers hooked up, plus hook up the antenna booster. This will take about 45 minutes, sez they. Between a store credit I have from a prior return, and the slight cost savings on the MBs vs. the RFs, I pretty much break even. Whew!
