Car speaker and stereo speaker?

Question

are car speakers dc?

and if so, could i take a car speaker, and switch the wires on the car speakers connecting to the voice coil with stereo wires that would be found on a stereo speaker and it would then be a stereo speaker?

Answer 1

Car speakers are not DC or direct current, if you run a direct current on any speaker you will destroy it because it has inductive properties. Car speakers tend to have a nominal 2 to 4 ohms rating while home speakers are 4 to 8 ohms. You can use any speaker wires , either for home or car, the only just make sure the + and -  is lined up to the corresponding + or- connector  for correct Phasing.

Speakers, being made to work with alternating current waveforms, don't have

a "positive" or "negative" polarity per se.  A single speaker will work

just fine connected to an amplifier without regard to polarity.

Multiple speakers, on the other hand, must be phased correctly to work in

unison properly.  This is true for multiple speakers within a single

enclosure, or a set of speaker connected to multiple amplifier channels.

By "correct phasing", what's required is that all the speaker cones

move in the same direction when the source amplifier(s) apply a voltage of

a given polarity.  This synchronization ensures that when the amplifier produces

a positive voltage, all the speakers compress the air in front of them.  If

care is not taken in this regard, some speaker cones are compressing the

air while others are expanding the air -- effectively, the speakers are

working against each other.
