Im using a multi meter
to ohm setting
i have a Alpine R-W12D2 Subwoofer. dual voic coil

It doesnt matter how i connect it the multi meter shows 8ohm?

how is this possible if this is a new certified 2 ohm subwoofer?

Can someone help me as I have 2 of these subs and I have a 1000 watt RMS JL Audio JX1000/1d amp but i believe it runs at 500 watts if the subs are 4ohm

Just really confused, and figuring the best way to wire these subs, but the 8ohm showing doesnt make sense unless im doing somthing wrong?

Take the Jumper out and test each coil individually - DC resistance on each should be around 1.8-1.9 ohms.

Could be a factory goof, dual 4 instead of the dual 2 ohms coils noted.

My advise check your meter on any other speaker without a crossover connected to that speaker car speakers are typically 4 ohms but readings between 1/ 8 ohms is possible compare your reading with the sticker on the speaker if all is good we know meter is good
Now remove jumper cable that is link wire from subwoofer terminals checker each coil individually red to + Black to negative - terminals are next to each other as a pair check reading should be 2 ohms
 
Wrong setting used on the meter. There are tutorials on how to use them properly for the need. You can also be able to download the specs for the unit and find a manual as well . 200k isnt going to justify the value to determine the proper ohms reading without setting it as its intended use 👀 👀

Running a 4ohm single voice coil sub at 2ohm?
2x 4 ohm coils can be wired parallel to 2 ohms or series to 8 ohms. There's many amps with 2 ohm power you can use.

I need help! I have one kicker 12” L7s 4ohm and one kicker L7r 2ohm going to a mono block amp.
Mixing a L7R and L7S may not be a good idea.
