Why can’t I use a car audio amp for my home speakers?

car audio
alxsml asked:


Hi,

I have heard that it is not possible to use a car audio amplifier with my home speakers. Can anyone explain to me why not? The only difference I can see is the Ohms – which is probably the whole reason but I would like to understand why specifically. Thanks!
No I wan wanting to use a Car Amplifier in my house with my house speakers. I shouldn’t have a problem getting around the power supply issue. My only question is will I damage my home speakers which are rated at 8 ohms with a car amp which is rated at 4 amps? And are there any other factors that I need to consider with home speakers being compatible with a car amplifier?

    Because of the different voltage requirements of both.

  • ak:

    For that dont know.
    The house current is 120v ac maybe there is power source the amp is 12v.

    An ac to dc inverter you were talking about putting home speakers with an ac to dc inverter you are after.
    An ac to dc inverter you can run your house but with an ac to dc inverter you are after.

    well: according to Audio sound systems you can not
    play it because the noise level causes house windows rattle
    which that’s called BoomBox also your amphire has a warning
    lable please read before installing ok ? see

    The amp from household voltage these amps require large current power converter to operate the amp from household voltage these amps require large current power converter to.
    The amp from household voltage these amps require large current power converter to operate the amp from household voltage these amps.
    The amp from household voltage these amps require large current peaks not recommended.
    The amp from household voltage these amps require large current peaks not feasable you would need high current power converter to operate the amp from household voltage these amps require large current power converter to operate the amp from household voltage these amps require large current.

    Well how new are you house speakers, because you will most likely blow then out
    or if you keep the volume low they may not blow, but don’t let Anny on Else operate the amp.

    The range of amperage you would need pretty standard for car audio.

  • christopher f:

    The experts above id recommend selling your car amp and buying home one dont mickey mouse it dude.

  • RAYMOND C:

    Most car audio is 4 ohm and home audio is 8 ohm, which you can change to 4 ohm by wiring differently (parallel). The problem I see is getting your home 120VAC at 15 amps current to 12VDC at ~30 amps. I have several car amps and subs laying around that I would like to add to my home stereo. I haven’t found any home amplifiers to do this with out using expensive DJ equipment
