    Why are car audio speakers 4ohm?

    Most home audio speakers are 8ohms, so why was it decided to make car drivers 4ohms?

    MO POWA!!

    Your 50 watt speaker is now a 100 watt speaker. Better for marketing purposes.

    That and those pro audio guys not knowing what they're doing. 16 ohms???? Sheesh! :poke:
    Just because you don't understand the data doesn't mean it's not relevant.

    Those pro audio guys need to get with the program :p

    Is there any sound quality advantage to a higher impedance?

    Pro audio mainly runs horns at 16 ohms, most cones are 8 ohms. Some run cones at 16 so you can get more on an amplifier.

    Some oem car stuff runs at 2 ohms, can't remember but bose may run lower.

    I believe that the lower overall impedance is due to the fact that you CAN get more power out of a simple amplifier that does not have a SMPS... trolls back to the older OEM stuff when that headunit or "booster" needed all the help it could get.

    I used to know a guy who had a primer gray Toyota lowrider that had 3 Realistic eq-boosters mounted to his dash. His truck was lit up like a Christmas tree

    Most GM Bose stuff I messed with the 90's rested at 0.45 Ohms.

    I had friends that would bring me burnt decks and amps they destroyed trying to run them.

    Is it stupid of me to think that less turn around the coil resulting in a lower impedance, can also mean lower inductance?
