So, I'm currently putting together an install for my '07 Mazda 3. I'm getting ready to install my new head unit, when I stumbled across a question that I can't really figure out a good answer to.
I bought a dash kit that installs my new head unit on the top of my dash (see http://cgi.ebay.com/ebaymotors/69-Mazdaspeed3-DVD-DASH-INSTALL-MOUNT-KIT-MPS-3-ONE-DIN_W0QQcmdZViewItemQQhashZitem2c4c749fc1QQitemZ190261272513QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories). For aesthetic and informational purposes (clock, temp, HVAC info, etc.) I'd like to leave the old stereo & LCD screen not only in place, but also still partially wired in. Now, I figure wiring the speaker outs and antenna to the new head unit exclusively should be easy. I'm concerned about the power. Can I split the main power and remote wires to both the old stereo and the new head unit, or will that end up underpowering both of them? The last thing I want to do is fry one or another, but I'm hoping to try and avoid running a new power and remote line just for my new head unit.
Any and all wiring advice on this would be greatly appreciated.
