How to determine If my subs a dual 1 ohm and 2 ohm

I have a Fi btl 18" and bought off a guy used. I'm getting another and I need to know if the one I have is D1 or D2... Anyone know how I find that out? Thanks

Check it with a multimeter. If you don't know anyone who has one (unlikely) they are pretty cheap and you should have one anyway..

i think Fi writes it on the voice coil too. check to see if it says like D1 or D2 or something like that.
