Hey everyone so basically i have a 08 g37 coupe with bose and I'm doing over my system. Tired of the limitation that bose offers. I have jl audio coaxial for the front and rear with a jl audio amp. Ill be installing a audio control lc6i as my line output converter. Ill be running all new speaker wire to the trunk.

How does the audio control lc6i get signal for sound? (Hopefully this makes sense)

Do I hook up the radio to the lc6i?
Or
Do I hook up the factory bose amp to the lc6i?

 

You can grab the signal from the rear of the radio or you can get it before it goes into the amp(s)

Search my user name of factory wiring diagrams of the bose set up. It will show you which wires to tap into.
