    d1 sub wired at .5 ohm is reading 1 ohm?

    So I have a d1 aq 12" hdc4 and wired at .5 ohm. I already put it in the box and I just started wondering what its sitting at so I checked it. I took out my dmm and it went down to .8 but sits at 1 ohm exactly. Is this normal? I also checked it from the terminal from outside of the box. thanks

    Yes, this is normal. With box rise you will probably sit even higher...

    It's normal for the readings to jump around, my 15 was a dual 2 and when i wired it to 1 ohm it was anywhere from 1.3 to 0.7

    I think you are fine... I mean someone else can chime in, and correct me if I am wrong.

    yeah, its just it freaked me out because its a d1 and i have it wired at .5 ohm but its reading it as 1 ohm.

    You are fine.

    Average dmm's aren't really that precise down near a dead short, so the .8-1 ohm fluctuation isn't surprising or alarming.

    More importantly "nominal impedance" isn't exactly the same thing as DC resistance. (DC resistance is what you were most likely reading)

    ~1 ohm on a standard dmm could very well be (and most likely is) half an ohm @ some frequency in the sub's intended frequency range.
