I am looking into a 2009 G37x. I am a bit of an audiophile, and I currently have a single DIN deck I love, some higher end speakers (not sure on size) and a 1000w amp and 12" sub.

I realize that the sub might be impossible, but is there a way to get the head unit in there and speakers (or other aftermarket high end speakers)? I know the current system and dash is fairly integrated. Is there a case for putting the deck somewhere else where it is still visible?

Or am I just dreaming of the impossible and if I want something more, I get an amp and speakers but use the factory system? Is this just a dumb idea altogether?

 

you can hide a deck on the center arm rest with heavy modification.

I went the external processing route.

I have a bit ten D that is mounted in my trunk.

You run your factory speaker wires to the processor.
From the processor you run rca cables to your amp.

You can control the volume from a controller or your head unit
