The signal from the head unit is a pre-amplified signal in the 2007, so you do not require a LOC. You will probably have to do some twin lead to RCA handiwork, and then you can plug straight into the Amp(s). I decided to put a 360.1 LOC from Rockford Fosgate to contol EQ and output to speakers from a PDA, wirelessly (Techie alert).
If the 2009 has the same Bose system, it's likely to have similar wiring.
