I want to attempt something like this but I dont need a 4 port usb hub.
Also dont like to use another cig charger in the back panel..

If i grab a usb header, is there anything behind that aux-in panel that I can splice and supply power to usb ports to charge iphone, etc ?

There is power back there (e.g. for the cigaretter lighter outlet), but you'll need something to step it down to 5V for USB.

But you would still tap off the existing cigarette lighter ? just wondering if there is enough juice to support both sides.

I don't understand why you would want to make it so complicated when there's a simpler solution => http://www.cellphoneshop.net/usbcar.html

I would want an aux outlet that can also charge while playing tunes.

1 gps
2 iphones

I already have a dual usb cigarette adapter. I'm 1 usb port short.

The cigarette lighter circuit is already fused for 15 amps - something like an new iphone is going to draw maybe a maximum of 1 more amp. You can get a pretty compact voltage converter for that kind of low amperage, if you want to keep a 'flush' appearance for another USB outlet on the lower panel.

Another option, as you've already got 2 other USB devices you want to use concurrently, is to just add a 12V powered 4 port hub like this one. It would look after all your USB requirements and get rid of the plug-in adapter you're using now.

sounds good..

I'm thinking of using 2 of these . All I need is 2 holes for cable to go through, screw it to that aux in plate from the front.

and in the back, setup something similar to the z4 post above
