I am interested in a similar setup and was wondering if there is a line-out signal amplifier/booster. Something available that is a simple plug in device. I am looking into something similar to this setup and would hate to have to crank the amps for the mp3 and then switch to the headunit with the same settings

thanks.
ps sorry for bring back the dinosaur of a thread.
