My radio is in the middle of a building out in the country and I can't
seem to pick up am radio. To solve this problem I tried using speaker
wire to extend it approximately 25 feet to the window in the office
next door reconnecting it to the loop antenna that came with the radio.
I had no luck. Is speaker wire an effective way to extend an AM
antenna? If so what would be the best way to get better results. I
thought maybe tinning the end of the speaker cable that goes into the
radio , as well as soldering the speaker wire directly to the am
antenna instead of just wrapping it might help. Any suggestions are
appreciated.

The 25 feet of speaker wire has become a capacitor across the loop that
you re-located. That detunes the loop and produces a low impedance shunt
across the front end of the receiver.
If you are interested in one particular station, it is practical to
build/buy a tuned loop AM antenna. Google will guide you to a few
practical designs of AM loop antennas.
