you mean 1 ohm or 4 ohm

Right...2 ohm DVC subs can only be wired at one or four ohms (with one driver). Since that amp isn't stable at 1 ohm, you're going to be stuck at 4.

i have it wired at 2 ohm right now, so should i just re wire it to 4 ohm then?

then your only using one coil , not both

sorry i am new to DVC and subs, what would i get out of the using both coils? wiring it to 4 ohm?

Go ahead and check your impedance with a DMM. You're either running at 1 ohm or you're only running one of your coils. Either case = no bueno.

Using both of your coils is basically using your sub to it's full potential. Wiring to four ohms would reduce the power your amp will be able to send to your subwoofer, but at least then you'll be running it the way it was designed to operate.

i am running 2 ohm, i checked before i wired it

So you're sending 250w (probably a bit more) to only 1 coil on a sub that's rated at 250? How long have you been running it this way?

you have it wired wrong, google how to wire up a single duel 2 ohm sub

ok thank you all, i have been running it for about 2 months, will this hurt the amp or sub?

this is how i have it

I Guess i need to do it like this

correct, hopefully the sub will be fine.... also don't forget to retune and reset all your settings too

i am sure it is, b/c i set my gains with a cd which was 4v and then i mainly play my music through the aux port which is about 2v so i do not get much voltage with aux, i tested using a Oscope and not getting much voltage to hurt anything, but i am going to re wire tomorrow and reset my gains, will it make my sub sound any better?

yep, i'd say you'll see a huge improvement
