I have a 2013 g37 with Bose and nav. I recently installed Tesla screen and 2 10” subs next I want to install a lc8i and a 4 Chanel amp to boost door speakers I have both already. What other materials are required and can anyone give me a general rundown on what I’m doing here.

 

If I was you I would try asking Crutchfield.

 

I added an amp/sub/dsp off the factory Bose setup, and thought about crossing the mids in the doors differently per some things I learned in @milosz 's Bose Bible thread: https://www.myg37.com/forums/audio-v...-analysis.html

Never considered replacing since its such an iconic feature of the car, despite showing its age a bit.
