Amp add on with bose help

[varycoolman579]

Im planning on installing two 12" subs in my 09 Tahoe and I want to use my factory Bose amp and nav unit and add a second amp for just the subs. I have some knowledge of wireing amps and subs but not with a factory amp and head unit. The main thing im stuck on is how to wire the second amp (Power, sound, etc.) the rest I can handle. Also what additional hardware do i need? Any input helps.
Pics greatly help too

You must use something like this http://m.ebay.com/itm/like/26188554...17182-37290-0&rvr_id=837804930472&_mwBanner=1 I use this on all my customers factory radios each and every time and they are so happy and pleased on how well it aftermarket subwoofer sounds with the factory system

Can i just use this? http://www.canadiantire.ca/en/pdp/e2-speaker-level-line-out-converter-0350066p.html#.VWy75M9Viko

And i need help with actual instillation more then just the hardware like witch wires to splice and how to run the power

Wire in you LOC to the output side of your factory amp. Usually located in your center console under your cupholders.

alright clearly you guys dont understand what I need help with, i know i need to hook up the LOC to the output side of my factory amp. But i need colors, theres no two ports that say output. and 12 volt doent have a diagram for a 2009 tahoe. All i Simply want is the colors i need to slpice to get sound from my factory sub to my aftermarket sub
