Dual 4 Ohm or Dual 2 Ohm
 

Hey this should be an easy question to solve.
How do I know if my Sub woofer is Dual 2 Ohm or Dual 4 Ohm?
Subwoofer is a Kicker Solobaric L7

If you cannot find the answer deliberately on the speaker or any of the packaging/ manuals it came with, assuming you bought it from somewhere else, find the model name/number on the magnet. Most likely it will either have a "d2" or "d4" in the figure, or even just a 2 or a 4 mixed in. Or........... hook it up to a dmm, :p

hey try this wiring site to if you like..I know it sure has helped me...
