My Civic had the upgraded sound system as it was an EXL model. FM sounded fine as well as CD and AUX modes. However, The AM side wasn't that great, sounded like a drive thru speaking comparted to The AM side of the radio in my Passat, which sounds fantastic. I still like Honda's just not The AM radio so much

The worst one though was on my 1996 GMC Sonoma, it was totally unusable, When the truck was off it was ok, but when it was on nothing but static and when you would go to accelerate, say merging into traffic all you would get was static that sounded like someone just ate taco bell.

However, the one on my 1994 Buick sounded great and even picked up AM stereo. Although, the power antenna option always got stuck when it got super cold.
I realize AM radio is slowly becoming a thing of the past but was wondering what others experiences were with car radios and The AM side of the dial.
