Poor Am Reception
 

The Bose Symphony sound system is incredible, but the AM reception is excrutiatingly poor. We have a 50,000 watt AM station here in Cincinnati (700), and I have trouble picking it up more than 50 miles away. Lower-powered AM stations are almost unavailable unless within a few miles of their towers.
FM reception is OK, so it's not an antenna problem. BTW, my Chrysler Infinity system picks up that AM station 500 miles away! Still stock antenna on the roof (Avant model). Any ideas on what I can check, or add (short of replacing the whole unit)?

look in the Symphony manual.. theres a part that tells how you to access the menu. There are two settings for radios

Re: Poor Am Reception
 

the local one will cut out all but the most powerful stations. you want to make sure your radio is set to the other one.

I have the same problem with the Audi Symphony stereo in my 2000 A6 2.8. It's not the local/distance mode for the antenna. Dealer tells me I need a new wiring harness, diversity box, and booster to make it better all at the low-low price of $818.00. Seems excessive just to get good am reception. Be interested to know where I could get these parts aftermarket.

if the power antenna isnt working, you'd need to replace that regardless of your stereo setup.

not quiet sure what a diversity box or a booster does... did they tell you?
