i admit im new to this. i bought 2 12" alpine r series subs a couple of years ago at a sound sensation in auburn. thye installed them in a carpet box and in my jeep. totaled my jeep 2 weeks later and removed them. stil havent got a car worthy enough to put them in. theyve ben sitting in my house unused since. im trying to sell them now and i dont knw if they are 2 ohm or 4 ohm. i have the original application guide but there are no model numbers on the sub itself or the box. can anyone help me out? its either swr-1221d for 2 ohm or swr-1241 d for 4 ohm, but i dont know what i have ? any help would be great . thanks
