    Re: Is it dangerous to run 800W speakers without amps

    the Pioneer head unit is rated 50Wx4 but that is a MAX power rating, and only attainable for a second with a lot of distortion.

    Even the 22W RMS rating is at too high of a distortion level to be listenable.

    In reality, you get about 12Wx4 out of a head unit with audible distortion. It's enough to be "loud" but it doesn't sound very good.

    a good amp rated 35W RMS x4 @ 4 ohms and 0.05% THD would sound amazing in comparison, and play much louder while sounding good.

    when discussing power you must discuss distortion. the internal amp in a head unit is an IC amp, no bigger than a credit card. compare that to an amp the size of a text book and you can figure out that one will be MUCH better than other.

    when you evaluate amplifier output you need to consider the following:
    * RMS power rating
    * Impedance load
    * THD at power rating and impedance load
    * duration of power test (one second vs one hour)
    * damping factor
    * amplifier Class (A/B, D, T, etc.)



    have you been helped by me? i'd love to know. shoot me a PM.

    Re: Is it dangerous to run 800W speakers without amps

    it's important to set the record straight so n00bs who find this while searching don't get the wrong idea.

    and it's pointless to flame someone for asking a question. people who flame n00bs are usually idiots who don't know the right answer, so they bash someone else.

    if you have useful and educational information to provide, do so. if all you can do is bash people for asking questions you should STFU (not directed at you on1wheel1, just sayin').

    point is, people are asking questions which is better than just doing stupid stuff. nothing wrong with asking a question. everyone was a n00b once.
