adding subs with factory head unit

[2005GrandPrix]

i have a 2005 grand prix i had a 2000 i dunno if its the same cuz the 2000 had a bose and the 05 got a moonson

previous i used the pink wire for the remote wire could i still do tht on the 05

and with using a line out converter what wires do i come out of there are blue black yellow and another color i kno u gotta come outta the left rear but wht wires??

and if there is a better way which is the better way

04+ stereos don't have a remote wire built in. You'll have to use any ignition switched wire or fuse you can find.

The positive and negative wires are the ones you will want to splice into for the line out converter.
