Planning on using one of the Asus EeePC box as a carpc but problem is, all it has is a headphone output. Besides getting a 5.1 usb sound card, are there any devices that will take the headphone output, split it 3-way and clean it up to proper pre-amp levels? I've tried looking at car audio active crossovers and signal processors but they all require 3 dedicated stereo inputs. I really wish not to have to use a bunch of splitters.
