ok so I see some posts saying yes you can and others saying no you can't.....

2010 SCREW Lariat 6 disc w/SYNC

can I just splice a LOC in behind the head unit?

I am guessing this is just to hook up a single amp and a sub since you aren't saying for sure. Either way, i would recommend tapping in at the b-pillars instead of the back of the unit. The wires are much easier to get to there and makes it easy to hide as well, you could tap into the rear left and right through the b-pillars at both the front doors. On my 2010 Screw XLT with the single cd player, sync, and sat radio the speaker wires color and polarity were as follows:

LF
+ white
- white brown

RF
+ white violet
- white orange

LR
+ white green
- brown yellow

RR
+ brown white
- brown blue
