Look up Ohm's law. Should help
The wires in a toaster are composed of a metal that heats up when you pass a current through the wires. The voltage, current and resistance for the toaster obey Ohm's Law (Voltage = Current x Resistance). When the wires heat up this heat causes the bread to toast. The toast is not part of the circuit and is not involved in Ohm's Law.
Ohm's law describes the relationship between ideal resistance, voltage, and current. Voltage is resistance times current. It is a useful rule of thumb for non-technical people and not an absolute law.Another AnswerOhm's Law is probably the most misunderstood so-called 'law' in electrical engineering. What it states, in essence, is that 'the ratio of voltage to current is constant for variations in voltage'. Unfortunately, and this is where the misunderstanding comes in, is that Ohm's Law applies to hardly any load! It doesn't apply to most conductors, and it doesn't apply to most electronic components such as diodes, etc. For Ohm's Law to apply, a graph of current against voltage, for variations in voltage, MUST produce a straight line -and this is hardly ever the case! For example, if we tried to draw this graph for, say, tungsten, we'd end up with a curve -which means Ohm's Law doesn't apply to tungsten!It's also incorrect to say that Ohm's Law is represented by the equation, R = V/I. This equation is derived from the definition of the ohm, and NOT from Ohm's Law.To summarise, Ohm's 'Law' is NOT a law at all! To be a 'law', it must be universal (i.e. must apply in every case), and that is not the case with Ohm's 'Law'.
They are proportional to each other with a constant of 1/V, by rearrangment of the formula V = IR.
Ohms is a measurement of resistance between the amp and speakers. Most home audio is 8 ohm, if you run 4 or 6 ohm speakers you cut resistance down and get more power out of the amp. Say your stereo is 100X2 @ 8ohm, if you use 4 ohm speakers you should get 50% more power BUT the amp is working twice as hard and can burn up.

R = 1/[1/2 + 1/4 + 1/6 + 1/10] Add up the reciprocals of the resistances, and take the reciprocal of the answer.
The sound quality won't be very good
If your home receiver is not rated for a 2-ohm load (many can handle a 4-ohm, but not a 2-ohm), you will damage components inside the amplifier by over-current. Don't use car stereo components in home stereo equipment. It's like using a hockey helmet to ride a motorcycle.
Don't know how you have subs wired but should be 4 ohm load is what your amp will see.
If you are trying to pump a 2.4 ohm sub with a 2 ohm rated amplifier you should be fine. The rating on the amplifier is the least resistance it should have on its load. Anything less than 2 ohms would fry your amp.
If you connect two 8 ohm speakers to the average car amp, then yes, probably. Most car amps can handle a 4 ohm load, which is what it would be.
This question makes little sense. Could you say what model amp it is? With two 4 ohm subs, you can either do 1 ohm or 4 ohm. Now if you have a bridgeable two channel, I think you can do a 2 ohm load. For a 4 ohm load, two 4 ohm subs, connect both positives from one side of the subs to the positive out. Then the negative coils from the opposite side (other side of the sub) to the negative output. Then connect the remaining negative and positive together on each subs. Look here http://www.the12volt.com/caraudio/woofer_configurations.asp
You need to calculate the equivalent resistance. For instance, if the three resistors are connected in series, simply add all the resistance values up. Then, you calculate the current (in amperes) using Ohm's Law (V=IR); that is, you need to divide the voltage by the resistance.
Ohm's LawVoltage = Current x ResistanceResistance is part of Ohm's Law. Not sure why you think there is some violation of Ohm's law as it applies to resistance.AnswerHardly any conductor or electrical component (e.g. diodes, etc.) obeys Ohm's Law. For Ohm's Law to apply, the ratio of voltage to current must remain constant for changes in voltages. In other words, if we were to plot current against voltage, for variations in voltage, then we should end up with a straight-line graph. But most conductors and devices produce curved-line graphs!The reason for this is that Ohm's Law is simply NOT a 'law' in the sense of being 'universal'.The equation, R = E/I, is actually NOT derived from Ohm's Law, but from the definition of the ohm.
Why should an amplifier think it is better to have a heavier load? Use the 8 ohm speaker. If your amp has a 4-ohm output you can strap a pair of 8-ohm speakers in parallel across it to match impedances. When impedance is matched to the amp, maximum power transfer happens. A mismatch doesn't let maximum power get transferred. The sound of speakers that are matched in impedance with the amp will be the same as the sound of mismatched speakers at low power. At high power (high volume), you can end up with some problems. Talk to your local audio guy and get up to speed. Take a couple of cold drinks into the store when things are not busy, hook up the audio person with a beverage, and then open your ears and pay attention. You'll learn a lot.
