Most of my listening in the car is speech radio, in particular Five Live. Trouble is our AM reception is lousy. My main objectives are better radio reception, & smoother, richer sound that doesn't hurt the ears when the volume is pushed up a litle. I won't be doing this work myself (if I do it). It'll be a job for my local car radio specialist. I'm just trying to get a handle on what sort of hardware I should be considering.
