Will a house subwoofer work in a car?

Answer 1

Yes, A house Sub Woofer will work in a car {if you park in the living room} lol. just kidding.

However there is really no such thing as a "house sub-woofer". A sub-woofer is a sub-woofer rather you put it on a stage in front of a gazillion people or on a submarine beneath the polar ice cap it doesn't matter. Its a speaker and it has two ratings that determine how it must be powered to operate efficiently.

Watts (voltage) and Ohms (resistance). Make sure that the speaker is rated to the amplifier that powers it. Generally Mobile audio systems operate with 4 ohms resistance and home audio operates at 8 ohms resistance but that rule applies seldom or never when using a sub-woofer or any type of exterior amplifier or crossover or pre-amp or filter or anything at all outside of two speakers one amp. So always check the max. watt output of your amp and make certain it does not exceed the max. watts rating of the speaker and the ohms rating of the speaker should never be lower than the ohms rating of the amp. For optimum sound performance the ohms rating and watts of the amplifier should match the speaker in any audio application.
