Hi Adam -
I'm installing in the glove box - I wanted access to the computer's DVD slot (either by reaching over or having the passenger handle it). My jeep has the standard speakers - I'm replacing them all with Focal speakers, and JLAudio 10w3 subs in the trunk. The guy I'm working with is doing the sub boxes in vinyl to make them look like the current factory leather. He's also doing the dash fab work (glove mod to hold the Mini but still give me access and removal - mounting the Hubs (usb/firewire hub under dash but not visible and the small Kensington usb hub in that little slot at the bottom of our dash console) - and he's redoing the dash to make the screen look like it belongs - I got the shroud, but I think he's got other ideas lol). I'm hoping the external Edirol usb audio interface will give me better sound than the built-in audio out of the Mini. I can either do a cable straigh out of that built-in port to RCA (have monster cable) or use the USB Edirol and use its RCA outs to the Amps (JLAudio 500/1 for subs and JLAudio 300/4 for Focals).
I also found tonight that my installers carry Optima batteries, so I'm going to go ahead and get a Red Top under the hood and a Yellow Top built into the back area near the subs box - both batteries are built for slow drain, so hoping that helps with some of the usb-powered hub issues that I'm anticipating while the Mini sleeps. At least it will buy me time while I look for a different hub - or don't if it handles the drain well or Mike from Carnetix figures out how to make me a USB cable that won't supply power - hehe. I'm powering the Mini with the Carnetix P1900 (+18 to Mac, +12 to Screen, +5 to Hub).
My install starts tomorrow and will go through Wednesday - I sure hope they can get it done by Wednesday night. I'll take pictures tomorrow morning before they get started, and I have permission to stop by and take some pictures during the process. Of course, I'll also have pics of the finished product when all is said and done.
Hope that helps and feel free to ask any other questions or make any comments or suggestions you have! I'll be really excited to see and hear about your ideas and experience.
