Hi Scott,
You will have to use your factory speaker. Your speaker has a "field coil" on it that serves two purposes. It has about 300 or more volts going through it to act as a magnet for your speaker that works with your voice coil to move the speaker cone and it also is used as a choke in the power supply for your radio known as a "PI" configuration. Look on your schematic and see part number 56 it ties in with positive ends of your two filter caps. Thus the "PI" name. Without this field coil you would not have any B+ for your radio.
Hope this helps
Terry
