    is there a difference in ohm rating on subs

    i have purchased a kicker solobaric 10'L7 sub. is there a difference in ohm ratings... 4 ohms and 2 ohms.... which is better .... is there a difference in performance.... using a pheonix gold octane r 4.0:2 bridged at 4 ohms at 400 watts

    Ohms makes no difference in performance, it just allows you to have different wiring options. What impedence is the woofer that you bought?

    the lower the impedence (ohms) the more power you will get
    ohms are a measurement of resistance, the lower the ohms the lower the resistance
    lower resistance means more room for distortion

    Uh... no. Lower ohms just means that the subs will draw more power from a given amp.

    You need to balance the total impedance (ohms) of the subs to your amp. From what you said, the amp wants 4 ohms to run bridged. So get either a 4 ohm sub or a dual 2 ohm and wire the coils in series for 4 ohms.

    Try looking around on the www for topics related to Ohm's Law to better understand how your stereo works. This will lead, believe it or not, to a better sounding system as well as an easier installation.
