I'm going to be selling my 99 vette and buying a friends 03 G35 Coupe soon and am planning to get an AVIC-D1 and move my stereo from my vette over to the G35.

I've got a pair of 6.5" CDT separates and some 5.25" CDT coaxles along with a Infiniti Perfect 10" in a vette specific box and two mediocres amps. I understand that the G35 has 6.5" fronts, so I'm fine there, will the 5.25"s fit in the back and am I going to miss not using the 6x9's?

Can I tap into the factory speaker wire or should I just run new wire?

Is there a remote power tap for the amps inside the car or do I need to run it through the firewall? Does anyone have instructions on that?

Any 10" sub enclosures you can guys can recommend that are about 1 cubic feet and fit nicely in the trunk?

 

I'd try the factory wire. Not exactly sure on the rear fit, but many would agree it would be better to sacrifice the rear speakers anyway.

As for the 10" enclosure. You arent going to beat the quality, fit & finish, and space than the 4080 box. Once you get 5 posts, you can give "4080" a PM and get a quote on the box.

Here are some pics. Very clean:
