if i wire the sub in parallel i should have a 3ohm load, i have never seen or herd of a 3 ohm load. is it safe to do it on that amp sence its only 2ohm stable?
and if the amp puts out 850w rms (at 4 ohms) and 500w rms (at2ohms) would it be safe to say it puts out 675w rms at 3 ohms?

Running a 3 ohm subwoofer load with an amp that is stable down to 2 ohms is perfectly OK. You have the numbers for the amp wrong though. As the impedance (ohms) goes down the more power the amp will produce. To a point. According to Crutchfield's web site the amp produces 500W @ 4 ohms and 850W @ 2 ohms. So your figure of 675W @ 3 ohms is correct.

JL's subs with dual 6 ohm voice coils were originally meant to be used in sets of 3. That way it allows you to wire the voice coils in series/parallel to get a more typical load of 4 ohms. With each sub's voice coils wired in series each sub becomes 12 ohms. Three 12 ohm subs in parallel gives you a 4 ohm final load.

ok thanks, and yeah it was late and i ment the ohms the other way around lol
