Think Stable = Safe. Your amp isn't over working or going outside of its threshold of power production.

The lower the resistance (ohms) the more power that can be pushed (watts) = More volume!


This is why when you see Amp power listings, they are broken down by Ohms.
For instance, my Kicker KX1200.1 amp right now has a power rating of:

1200 Watts @ 1 Ohm (Stable)
600 Watts @ 2 Ohms
300 Watts @ 4 Ohms

Notice how the power is dropping? That added power is being used to push through and is being resisted. To put it simply, you want a lower Ohm rated sub, but make sure that your amp is Stable at that Ohm rating. And that the power it's able to push at that impedance is within the limits of your sub.


Big please step in and correct anything I might have goofed on or omitted. This is how it's explained to me, but please correct me if its wrong.

So it sounds to me a 2 ohm would be better than a 4 ohm.

No, not true.

The ohm's of a sub doesn't matter, what matters is that you match it to the amp. a sub that is 2 ohm should be matched with an amp that makes it's most power at 2 ohms.

Which is a more in depth answer than what I posted, but the conclusion I was figuring he'd come to.
