    So when I installed my aftermarket radio, I noticed a loss of AM signal on my radio. YES, I listen to AM radio. So shut it!

    After doing some research, it came to find out that the 4runner has TWO antennas. One for FM, and a booster for AM that runs towards the back.

    Other's say that the booster in the back is for FM also. Regardless, I wanted to use that "booster" antenna to improve my AM reception.

    Since the aftermarket headunit only had connection for ONE antenna, I had to find some sort of adapter to go from two antennas, two one antenna.

    After doing some research I found a Y adapter, and an scosche adapter for the smaller antenna plug:

    On Amazon theyre found via:

    Metra 40-UV43 Male to Female Motorola Antenna Cable

    Scosche Mda-B Micro/Delco Antenna Adapter Tip

    I took my headunit out. I am not going to go thru those steps since I already discussed it here:

    https://www.4runners.com/threads/installing-aftermarket-radio-and-switch-panel-pictures.627/

    Once I pulled out the headunit, I dug around for the two antenna cables:

    The smaller one is for the rear antenna. The larger one is for the regular whip antenna that I was using to plug behind the headunit. The smaller antenna uses the scosche adapter before plugging it into the Y adapter.

    I then plugged the Y adapter into the back of the headunit.

    Voila! AM reception is now improved!

    If it makes you feel any better I need to listen to AM for football games on my way home from work.

    because of the damn time difference radio is all I got.
