sure you can change the ohm load at the amp by adding speakers, but that's adding speakers. The OP could do the same.

Don't get completely stuck on the #s.
The resistance of a speaker is measured at a resting state. A speaker is an electric motor where the resistance is constantly changing as the voltage is applied and varied, creating sound.
You put said speaker into an enclosure and the working resistance will change again,it is called box rise.
So your 2 ohm speaker and 4 ohm stereo will play fine together.

Not to split hairs BUT impedance is the AC equivalent to resistance and audio output is an AC SIGNAL 🙃🙃

Yes, that's why it's impedance. Just nomenclature. Lol.

You can get a 2 ohm resistor that is a wattage rating equal to the 50% of the amp output and wire it in series with the speaker. Some amps will tolerate a lower impedance some won't.
Search amazon for 2 ohm 25 watt resistor
FYI I worked on car home and pro audio since 1969. When you let the smoke out they don't work as well. When radios were over $300 I made good money repairing them. Now their throw aways.
