what is the difference between all of those 3 in power consumption i seen a old kenwood house amp that is almost loud almost good as a dj amp

    The first one is to be used by "Professionals", the second one goes in your "home" and the last one works in "cars".

    Next question please.....

    Shouldn't that read...."I seen a old dj amp that is almost loud almost good as a kenwood house amp"?

    This thread makes me want to cry.

    Pro-audio or "dj amps" are for public address systems. They are high sensitivity amps with noisy amplification circuits that are doing nothing but shouting everything through high sensitivity drivers that are designed to do nothing more than play loud. They have a limited frequency range and the only reason they sound like they are running the full 20-20K gamut is because of room loading. They are typically playing with more output than the room can handle because DJ's are morons and don't understand what "reasonable listening levels" means. So the drivers are playing at levels that are moving enough air to actually get a compression factor in a room. That's why you can "feel" it.

    For critical listening of any kind, pro-audio is garbage. Anyone who says or thinks different is drunk off their butt or a moron.

    Home audio runs on 120V AC power. Unless you remove the AC transformer and connect it directly to a DC power source that can energize the internal DC power rails sufficiently to provide the power necessary to run the amplification circuits. But the 120V AC/DC transformer already does that so why bother?

    Car audio runs on 12V DC power. Well, actually, it's typically 14.4V DC but who's counting? Oh, that's right, I am.

    Home and car audio are way more similar than the vast majority of people think. In fact, many of the newer, ultra efficient amplifier designs in home audio were originally made for car audio where they were perfected while rattling people's kidneys loose and exciting pretty girls while blowing their hair around.

    Power consumption is entirely dependent on circuit design and the load you are driving (i.e.: what kind of amp, how powerful it is and what speakers you have attached to it). To give you a reference for power consumption...yeah, impossible. You need to provide specs for what you are looking at.

    Also, go learn about Ohm's law.

    As far as what power they use Pro and Home run on 120V AC power. Amperage draw depends not on how much output power the output circuits support but how much power the input circuits use. So you'll have to look at the specs for that. Especially if it's an integrated device that is running pre-amp controls that aren't passive.

    Car audio uses 12V DC standard. Most car charging systems run between 14.4V and 15V so that they battery actually charge to a 12V standard and you can still run the car. Again, you need to look at the spec sheet for the amp you want to use.
