It means that the loudspeaker maker tells you that his loudspeaker builds an input impedance (load impedance) of Zload = 4 to 8 ohms. In audio we use always voltage matching and so the amplifier output should have a source impedance of smaller Zsource = 0.1 ohm. Scroll down to related links and look for "Damping Factor".
wire two 8 ohm speakers in a parallel circuit!
Purely additive. 2+3+4+5+6=20.
16 Ohms. Yes 16 ohms in series. 4 ohms in parallel
5 ohms in parallel with 20 ohms is 4 ohms. 4 ohms across 200 volts is 50 amperes. However, resistance is a function of temperature, so the 4 ohms will probably be higher, reducing the current. How much depends on the temperature coefficient of the loads.
The speaker you connect to those terminals needs to be 4 ohms or greater.
this is range of 4 ohms resistance in an electrical device. Ohms is a measure of resistance in electrical qualities. Circuits and devices are rated , or measured for there resistance in ohms to meet a designed electrical need. Is this related to a speaker?
The difference between 2 ohms and 4 ohms is 2 ohms.
2 ohms of resistance
Ohms is a measure of impedance (resistance), not volume.
4 ohms
There are 4 ohms
Car stereos are designed for 4-8 ohms loads unbridged (8 ohms bridged). So wire it for 4 ohms. If you use a separate amp for the speaker then refer to the amp's documentation - most are designed to operate with standard 4 ohms unbridged and may also have provision for 2 ohms unbridged (or 4 ohms bridged).
It has to do with the load on the amplifier, you can't hear the difference.

There is no amplifier with an output impedance of 8 ohms or 4 ohms on the market. All audio amplifiers really have an output impedance of less than 0.1 ohms. Scroll down to related links and look at "Amplifiers, loudspeakers and ohms"
