Bypass Bose Amp and Keep bose Woofer?

Hello... 

I recently replaced my head unit on my 2005 GMC yukon with a pioneer avic-n1....  I also added two amps, one for two jl audio 10w6's in the back of the car, and another for mbquarts on the doors.  The way it is wired, I bypassed the bose amplifier and I installed an external speaker to the pac-0s2 onstar interface so that I can still keep onstar functional.  

Now to my main question....  I really miss the feeling of having a woofer up front in the center console and was wondering if there is any way to keep the stock bose subwoofer running along with the rest of the upgraded system?  Would I need to buy a third amplifier to power this woofer?     THX

If anyone that is familiar with bose stock systems can give me some info I would really appreciate it....  

I am just not sure how to start going about this???

Thanks!

Two questions:

1.  did you use the CM1 (chime module)?

2.  did you use the factory speaker wiring or did you run new aftermarket wiring?

it would be a good idea to amplify the factory woofer. You could run it off of the factory deck but you would need to use a cross over to get only low frequencies to the factory sub. That subwoofer is a dual voice coil four ohm sub. Probably not get a whole lot of juice going to it if you use the speaker outputs of the h/u. I nice little amp would be the way to go.

1) I did not use a chime module but am forgetting to turn on off my headlights when I have them on during the day so now I am thinking of getting one...

2) I ran wires from the amp to behind the head unit, and there I tapped into the factory wiring that goes out to the speakers...

I was actually thinking about doing that but am not too sure how to get to the wiring that goes into the sub... Behind the h/u there are wires coming out of the h/u for front and back speakers (to the amp I guess), and then in another part, they go out to the actual speakers (i am guessing from the bose amp -->these are the wires I tapped into with my amp).  But I cant find anything for the woofer. I am guessing that since the woofer is in the center console, these wires are going directly from the bose amp to the woofer, thus why I can't see them???   Any idea how to get to the bose amp in this car??

BTW....  Thanks for the help guys!

Any idea where to begin looking for the bose amp....   I am guessing it is in the center console but any suggestions on how best to get to it?   Thanks!

Jazzy...  I think I found it... 

 I took out the center console and found a silver colored aparatus that I am 99% sure is the amp.  It has ridges accross the top, kinda like the old fosgate punch amps but this one is silver colored.  The amp has two plugs going into it....  One plug seems like it contains the front and back door speakers as well as some other wires, and the other plug has the exact same color wires you mentioned in your previoius post for the woofer, as well as some other wires too... 

Can I just tap into those four wires that are going into the amp, and run them to my amp?      If so, how should I do it...  Join the two positives (green and blue/white) and join the two negatives (blue/black and GREEN/ black) and then run these to the positive of one channel and the negative of the other channel of the amp (bridge the amp)?   I have a kicker zr-120 that I can use to run this woofer, would this be ok or too much?  

Thanks!
