The way I see it now, people with Nav should be able to do this as well, just as long as they dont mess with the 10th speaker (or impedance match the old one with new one if they do want to replace it) because this is where the Nav voice comes from. Hope this sheds some light on the subject. For example, if the stock Bose is running off of 2 ohm speakers, and you replace them with 4 ohm speakers, then you are cutting the amplifier power output by one half. This is where you get the problem when people just replace the door speakers and use the factory amp. I've seen some Bose speakers for cars read as low as 1/2 ohm. It IS common for the Bose systems to have less than normal impedance for their speakers so they can extract more power out of the tiny amps they use on their cars. Without one of the two, I dont see how a speaker would be able to function, because of the way the magnet needs both sides of input in order for the speaker to move and reproduce sound. The Murano's had two going to each one, just like every other speaker I've ever seen. We shall see.Ībout the comment for the Bose speakers using one wire. If tradition follows, it should because all Bose systems up to 2004 have the same connector at the back of the radio. I am waiting on word to see if the same connectors are used in the Armada w/Bose. We sold the Murano and put it all back to stock and I have the Pac-Audio unit in my garage right now as we speak. The unit "T's" into the stock harness just behind the radio and gives the user front and rear RCA outputs for an amplifier, along with a remote turn on lead. I found a company called Pac-Audio that makes Bose interface kits that allow you to add aftermarket amplifiers to your existing Bose stereo system without cutting any wires. In the end, I replaced all the stock speakers and added two subs. I gutted everything except for the head unit, because the head unit shared the same circuit card as the HVAC controls. Before we owned the '05 Armada, we owned an '03 Murano w/Bose.
