was playing around with speaker wires, and connect a positive end to the amp, and the positive end to the speaker as per normal.
Then did the same for the negative.
However if i switch the wires around at the speaker end, (ie, wire connected to positive in amp, but negative to speaker) the speaker still works the same as if connected the other way.
Why is this?
Electronics isn't really my thing, but afaik its coz it's still forming a circuit no matter which way round it is wired - so it will still work.
However, the speaker will not be in phase which means that the speaker cone will move in and out at a different time to other correctly wired speakers, which mucks up the sound.
Speakers dont contain any real electronics (well unless its got a crossover built in), it will work, but as said it will be out of phase, which means in will sort-of move oposite than the way it should, when the speaker should be pushed out, it will be fully in, and the same is true otherwise.
Like the other says the speakers will be out of phase meaning your music will sound weird when played through the system.
As long as both speakers are wired the same way it doesn't really matter for most speakers.
if you have 2 subs in 1 box and connect out of phase they will cancel each other out.
if you mount 2 subs face to face you have to connect 1 out of phase so they move as one.
Thanks for the responses guys, may get a digital volt meter and confirm they are not out of phase.
no need, unplug one, if it gets louder they were out of phase
just did that to one speaker, and i unplugged one cable, and the sound did go quieter, therfore they were out of phase.Quote:

if it got quieter its in phase and working as they should, out of phase and the cancel each other out so unplugging a speaker makes them sound louder. if that makes sence.
how can unplugging one speaker make it louder?

So what should happen here to the left speaker in comparison to if the red wire WAS connected.
Should the sound just cut out alltogether or just be lower volumed?
If the speakers are out of phase then unplugging one may, in theory, increase the percieved volume of the sound because previously sound waves coming from the out of phase speaker cancel out the sound of the other speaker, because they will be inverted. In practice, how much this happens will depend on the environment in which the speakers are placed, so it might not be noticeable.Quote:

If one wire is not joined to the speaker then there will be NO sound as the circuit will be broken. All speakers do is convert an electrical signal into noise via an electromagnet and some cardboard, if there is no circuit, there is no current and therefore no sound.

From the Nyquist rule we know that we sample our audio at twice the rate we can discern. The way the ear works is its looking ultimately for a difference, be that wave from the cone going in or out, it will sound the same just be in opposing phase.
Now as god when he created man in his own image didn't like us much, he gave us rather poor hearing compared to dogs and the like (which therefore must be gods chosen race).
As such the only difference you might get is a volume cancelling effect that probably is only going to be apparent at lower frequencies (think of the cone moving slower with a margin of error, the fewer agitations the less effect the error has).
