    Can i hook up home speakers in my car?

    and even if i can't, i did yesterday.
    I blew 2 of the 3 6x9's in my '81 Cutlass so i had a friend hook up my two 200watt sony speakers that are in perfect condition.
    He said he's pretty sure that it's not good for the speakers and that they could eventually blow and crack to shit. is that true?
    Something about you shouldn't run home speakers on a 12volt system?

    Your friend is full of it. A speaker doesn't care if the amp connected to it has a 12VDC power supply or 120VAC power supply. As long as the power coming from the amp is clean there will be no issues.

    Just because your SONY speakers are rated at 200W doesn't mean they won't blow too. If your car stereo puts out lots of distortion when you crank it up you will blow the speaker no matter how many watts it's rated for.

    I've got a Sony deck/headunit in the car that's 52x4 watts and no amp.

    But your saying if i crank it too much they'll crack but other than that it's all good?

    Look the difference in house and home audio is most car audio speakers are either 2 or 4 ohm ... home audio is 8 ohm the impedance is totally different .. here check out this forum thread it should help you .. please dont listen to bullshit and waste your money blowing speakers

    Check the back of the home speaker. It should tell you the Ohm rating.

    You are blowing speakers because you are cranking them up to distortion levels without having enough power to push them. The voice coils (wire behind the woofer cones) are staying energized constantly when you turn your head unit all the way up and the bigger speakers may blow even faster than your 6x9's because you don't have power to move - just enough power to heat them up to failure (what you are calling a blown speaker). Think of an electrical motor in a bind, not enough energy to turn the motor over, but enough to heat it up.
