I need some clarification before I break something lol

Hey guys/girls! So I'm about to install "a system" in my '06 Forenza that I just bought. Now I've been searching this site and have been successful in finding bits and pieces of how to do this, but nothing that was detailed enough for me. So here's the low down on what I’m trying to attempt: I will be retaining the factory head unit as well as the 8 other factory speakers (for now); moreover, I am interested in installing these two 12'' Kenwood’s and an amp that I took out of my previous vehicle. So my two general questions to you are:

1) Does anyone have a detailed diagram/pictures for dismantling the AC sensors, etc., that I'll have to disconnect in order to access the back of the head unit so I can begin splicing?

2) Is there already a factory amp on which all the speakers are ran to? Some cars have them under the seat or something, but I have no clue about this car, just curious of how it works.

I do have one other question to ask, but it's off topic...can anyone send me a link for the FSM (Factory Service Manual) to my car?! Any advice to any of these questions will be greatly appreciated. Thanks for your time.

I used the stock head unit with my sub install, but I didn't bother trying to get to the back of it. I picked up an amp that accepts both RCAs and regular speaker wire as inputs. To get the signal to the amp, I spliced into my passenger side rear door speaker wires (if I remember correctly, the speaker wires are solid light blue wire and light blue with white) and ran the wire under the door molding to my amp in the trunk. I have no complaints about sound quality. Good luck! (2006 Suzuki Reno, NEW MODS - Charlotte, North Carolina)

Cool thanks for the idea.
