Head unit line level output impedance

Any suggestion for getting some volume out of a head unit that has a 3V/55ohm output? Trying to get it to match with the input of anything is getting to be not fun. I'm at the point where I am considering building a preamp from scratch on stripboard.

No one is that up on impedance matching?

OK...got it sorted. I had forgotten that THIS particular amp has a button for TWO input ranges. Press the button and VOILA!
