AM Radio reception
 

Has anyone had any problems with AM radio reception in their 911? My car when I bought it already had an aftermarket CD player in it, but the AM radio reception is terrible. It’s an Alpine, which is a good brand. I've tried running a new ground to the body, but it still sounds the same. I recently put a new Alpine HD radio in (haven’t purchased the HD tuner yet), but the AM reception is still terrible. When I install the HD tuner, will this solve my problem?

Appreciate any input,

Kevin
