I am planning on integrating an Alpine VehicleHub Pro with the Bose system in my 06 Murano without navigation. Basically, this component is designed to allow you to build an Alpine system around an OEM system that basically doesn't allow you to remove the head unit. Basically, it is a head unit, but without the in-dash part...just the "guts." It would sit under a seat, and the inputs to the unit are the speaker-level signals coming from the Bose amp. The system is controlled using their "Orb" controller, and you view the vehiclehub menus, etc. on the vehicle's LCD screen (which is interfaced using an aftermarket adapter such as nav-tv, etc.--I will be using the Peripherals PNVI unit because it will auto-sense which output needs to be displayed based on whether or not it has a signal from the vehiclehub, and won't require an extra switch, remote, etc. other than the Alpine one).
The first thing I'm going to use this unit for is to add Alpine's full-speed ipod interface. I would expect this to be a better solution than Nissan's interface, which last time I checked wasn't fully functional for 06's anyway. After that (after I save up a few more pennies) I'm going to add an Alpine navigation system. Bluetooth, other amps, USB interfaces, sound processors etc. are all other things you can add directly to the VehicleHub Pro.
I do see a couple potential issues here, and I wanted to get the feedback of the users on this site who appear to have a pretty good handle on the workings of the Bose system.
1. I realize that I'm basically "wasting" the Bose amp (well except for the sub, which will eventually get replaced), but I would bet the 18 W RMS from the VehicleHub Pro isn't that much less powerful in practice. BUT....it seems the consensus is that the Bose speakers are 2 Ohms at most, with the front speakers wired in parallel with the tweeters and possibly presenting a 1-Ohm load. I have a good feeling this may be quite harmful to the Alpine unit, correct? If so, I'll want to go ahead and replace all the speakers in the vehicle with the exception of the "sub".
2. As far as the Bose sub goes, I'm going to eventually replace it. I am wondering if the full range of frequency spectrum is sent to the front/rear speakers. I realize there are caps on the tweeters, and coils on at least the front woofers to filter out the lows from the tweeters and the highs from the woofers. What I haven't been able to determine from reading this site is whether the bass frequencies sent to the subwoofer are also sent to the woofers in the front and rear? This is important, because if so, I'll be able to manipulate bass and add a subwoofer directly to the VehicleHub Pro, and if not, I'll have to just grab the outputs from the Bose amp and connect to my new sub amp speaker-level inputs as others have done here. Not that that is a bad solution, but it would take away from the "seamless" integration of the Alpine unit by not allowing me to control bass via the Alpine (which has subwoofer outputs, crossovers, etc. built-in).
Sorry about the long first post...thanks for any advice!
