Everytime I upgrade to an aftermarket deck the radio reception always goes out the window. Usually FM is not that bad but AM is always horrible. I like to listen to the traffic reports on AM and also certain talk shows on AM if I am on a long drive. I was wondering if anyone had any tricks on this issue. The factory decks always have superior AM/FM reception. I guess the Antenna is tuned for the factory deck One thing that I did on my Evo is I bought a $12 amplified antenna and it really helped FM but AM is still a little weak. Most of the Evo guys put the Honda S2000 shorty antenna on which makes the bad reception even worse.
