    me too lol.. i pretty much always have the phase on my HU on reverse, sounds better for some reason

    So does that mean you can just take the pos and neg speaker wires from the subs and just put the pos wire into neg terminal
    nd then put the neg wire from the subs to the pos terminal on the amp and it'll be good? Right?

    yup

    And please don't get me wrong. I love you guys. The frustration stems from wanting more from you. You have to challenge yourself. You should be able to wire a Chevelle for a big block and 150's, and then go inside and make a cheesecake and do laundry. Have to get out of spoon feed mode and think for yourself and figure shit out.

    I totally agree with you. It's pretty easy to fall into that mode sometimes though. But in general, people need to just do things more often. You will learn the best by trial by fire. Mistakes are the best instructors.

    Re: mounting inverted

    In laymans terms: when the speaker receives a signal, it either starts cone motion by moving it out, or moving it in (remember, in its unpowered state, the cone is resting centered in its range of motion). If in its currently wired state, the cone starts by moving out, then reversing the speaker wires means the cone will start by moving in. This is why if you invert a speaker, you want to reverse its phase (by any of the means discussed already in this thread), because in essence reversing the mounting position of the speaker means the cone is now starting its initial motion in the opposite direction than it use to. This is most important to understand if you use more than one sub, but only invert one of them.

    As others have said already, you often want to have the subs out of phase with the rest of the speakers for blending purposes (poor man's time alignment), so unless you are only inverting some of your subs, or already have them blended properly but then want to invert them all, the sub's absolute phase (how its wired, backwards or not) is less important than what your ears say sounds best.

    Hope that helped.



    No speaker, in the history of speakers, has ever been blown by too little power. Ever. I don't care what your friend told you, he's a dirty liar.

    People rely on teh webz too much sometimes. Just read read read. DIYMA is a good place for info. Some good archives on here as well..

    Perfectly said, its like you copied that out of a book.

    Re: mounting inverted

    Good God, frantic n00bz in this thread. lol C'mon Garret!

    As Ciaonzo stated, You only use ONE phase changing method. Either the head unit reversing option, OR the speaker wire switching option, OR the amp phase switch/knob.

    Subwoofers move based on a Sinusoid of voltage. It alternates from positive to negative (AC-Alternating Current) so when you change the phase by 180 degrees, you are basically changing the polarity of the voltage (in layman's terms) so that the cone is moving opposite of where it normally would be. This is used in invert mounting so that the cone is still moving the same direction relative to the enclosure.
