Has anybody had success taping into the bose amp. I have a G35X with the bose system no NAV. I want to replace all the speakers in my car except the midrange top driver and passenger speakers.

I so far have 4 Sony XS-GT1638F with Massive SC 4.55
1 Kicker Comp C10 with MTX Mono Block TC3001
I also made MDF supports for the door speakers as there 10" woofers in there. so my 6.5 can fit.
I have a wiring kit. And a Hi/Lo converter for the amp.

But as i read online its a nightmare to swap the bose system and you have to keep the amp in order for the head unit to work. I also want to be able to keep my bluetooth capacity really handy for phone calls. Does anybody know what cables to tap into or how to upgrade the system in the car.

Here is a pic of the current amp in there.

 

I tapped in to mine but I cant remember which color of wires I tapped in to though.Try search first and also try youtube there was a video that somebody has. Not much help but better then nothing...
