AC vs DC speakers

[someolboy]

My kid has a pair of car audio, 12" boomers connected to his home audio amp... naturally they don't bump as they would if they were connected to a 1,000 watt car amp, ( thank God! ), but, my question is can this cause damage or eventual loss of the A/V receiver?
And what is the technical difference and requirements between AC & DC speakers?

Are the driver 4ohm ,8ohm,can your receiver handle the ohms.The problem is if the receiver as enought power for them .If the speaker at high volume start clipping the receiver cant handle them and might overheat.Pat.P

The power coming out of an amp whether it be car or home is DC. There is not such thingk as ac/dc speakers.

power coming out of an amp is AC not DC..... DC + voice coil = BAD!!!!!!!!

In actuality, the amplifier generates a completely new output signal based on the input signal. You can understand these signals as two separate circuits. The output circuit is generated by the amplifier's power supply, which draws energy from a battery or power outlet. If the amplifier is powered by household alternating current, where the flow of charge changes directions, the power supply will convert it into direct current, where the charge always flows in the same direction. The power supply also smoothes out the current to generate an absolutely even, uninterrupted signal. The output circuit's load (the work it does) is moving the speaker cone.

DC is direct current IE batteries. Get the facts straight before putting out bogus information.

Here's a link that explains how it works.

I find it hard to belive that you are an audio engineer and don't know the basics of how an amp works. I'm amazed every day by something but this takes the cake.
