    run .5 or 1 ohm

    i have a bc 5500 an im gonna be replacing my current speakers with xfl 15s but i wanted to get some input on what ohm load to get b4 i buy them, im running my current subs at .5 but i have the option to purchase either d2 or d4 15s of xfls..

    box is 13 cubes tuned to 35hz


    i was gonna just go .5 but some people say 1 ohm is a lil better sounding any input?

    Re: run .5 or 1 ohm

    lol is there really that much distortion from 1ohm to .5 ohm?

    Idk amp specs, but wouldnt the coils already be distorting the BL curve with that much power thrown at them?

    Re: run .5 or 1 ohm

    With a stout electrical I'd run at .5.

    BTW is your 35hz setup daily? Does it still get low? I'm tuned to 31 atm but switching to 2 12's that will be at 35, not sure if I will notice a difference.



    Current set up: 2010 Buick Enclave, 2 12" MMATS PROCASTS 2.5@35, MMATS D200HC
    Hertz 165XL comps in front door, Eclipse XA4000(switching to Alpine 1507)
    Pioneer Z150bt Nav, Audio Technix all around.

    66 Pontiac GTO, modified stock radio, Xtant 3150x, Trubass 8", Kicker KS6.5's in the front kicks.
