ohms

i am really confused about how ohms work?

would the power of 400w x 2 ohms be the same is 200w x 4 ohms?

the lower the ohms or impedance the more power going through the speaker

if you have a 4 ohm speaker it will receive less power than a 2 ohm speaker

if it is a 4 ohm speaker than yea it will prolly see around 200watts

so is it the less ohms the better?

no....amps just put out less power at higher ohm(most amps)

yes

ohms is resistance....the higher the resistance, the less power an amp can put out!

different vc's allow you different wiring options

yes

incorrect

yes, power is an amount of work done in a given time. impedance (measured in ohms), determine the required voltage and current to produce the desired power.

because amplifiers are designed with maximum voltages and currents, the choice of load impedance (the impedance of all attached speakers when wired up) will determine if the amplifier is optimally used, underused, or overstressed.

eg, an amplifier with a 32ohm speaker will put out little power because the amp will reach maximum voltage, and won't be allowed to put out anywhere near maximum current. likewise a 0.5ohm speaker would cause the amplifier to reach maximum current at an output voltage significantly less then the amp could do. since gain affects voltage output, its very easy to tell the amp to put out more voltage (and thus more current) anyways, overstressing the amplifier.
