I would abort mission with the in dash tweeters. You are better off purchasing a set of Component speakers from Cruthcfield and notching out a little hole in the door above the panel to install them. You can then easily disconnect the tweeter lead that runs to the dash and be done with it. I just ripped out the entire center dash consol to rewire the radio and I could not even come close to see how to get to the tweeter.

I should clarify that I don not have an Infinity system. Therefore, I can confirm that no sub exisits becasue I just ripped out both seats and carpenting to install an Alpine amp and a powered sub under them. The stock system is weak! The OEM speakers are rated at 15w. YUCK. The new system shoule be up and running this weekend.

Where is the factory a,p located? It is def not under he seat. Behind the head unit if you want to call it that?

It seems as though you are correct as I have no sub or amplifier. It looks like there is a speaker grill in the very back just above the fender wells that is there for an upgraded system. I still am dying to find a site that lists the specs for this car. The owners manual and DVD they give are useless. I agree that upgrading the speakers are a good start and will add clarity but will not create that deep full sound of adding a new head unit and or amp. We are at a distinct disadvantage with the Journey as it is only 5 or so years old, with a complete overhaul in 2011. Forum support is helpful but there is a limited knowledge from aftermarket company's and distributor such as crutchfiled. Especially for me who is coming from a 2004 Maxima with literally endless mods, support and documentation. I had a similar info screen in that car which was integrated into many of the vehicle controls as well. There was a well documented mod that moved the screen lower into the center console creating space for a new head unit to fit in its place. I say this because it seems look "possible" in terms of room, to move the current head unit lower and replace it with an aftermarket solution. Even if it is not deep enough for a full unit, a separate display could be mounted there with a amp located under the seat. Thoughts?

Are you guys sure about the sub-woofer in the car? I count six speakers, 2 tweeters in the door, and 1 speaker in each door. The two slots in the cargo area (which would seem to be a good place for the sub) do not appera to have anything in them. Where is the amp & sub located. Also what advantages does keeping the factory have? Sorry for all of the questions, it's frustrating not having any documentation on the audio system.

Seeing how there is not a cheap way to upgrade to factory uconnect 4.3 head unit in my 2011 Mainstreet, I want to explore upgrading the other components. Is there somewhere that lists the specs of the systems? Watts per channel, preamp, ohms etc. I have thoroughly checked Crutchfield and even they do not have information listed.
