Ohms Resistance is a DC measurement.
Ohms Impedance is an AC measurement.
You can measure an sub with an Ohm (DMM) meter, what you see is the DC resistance.
The reason its impedance is car amps are emitting an AC type current which varies. Which is turn produces the curves needed to generate sound.
The Impedance of the sub is constantly changing while in use. A simple way to see this is to plug your ohm meter into the sub unhooked. Press on the cone. Watch the needle/numbers jump.
So to sum it up. Amplifiers dont "produce" ohms. What your looking at is the stability of the amp, what it can handle. Also the power output at the given ohm load.
To get even more technical, amplifiers DO have "ohms". Since it is an electronic circuit, there is some resistance. If there wasnt, it would be a dead short
. But this resistance bears no affect on us or our situations.
so there.
