MB quart recently updated their amp-less kit to also include an adapter that utilizes both the stock tweeter and mid-range wires in the sound bar. Contact them and they'll send you the extra adapter for free. Otherwise, you'd have to splice the tweeter and mid-range wires together to get the full signal range.Got the MB Quart adaptors installed today with some Infinity Reference 9632's and greeted with warm shit. Muffled garbage using the MB Quart speaker adaptor, not sure but looks like they are right polarity. Disconnected the batteries hoping to reset the system, but still garbage. Should I use the "tweeter" connector instead of the "midrange" that was supplied?
