Voice coil Question

[BigOleDom 10+ year member]

Ok, about a month ago I bought 2 rockford fosgate punch stage 2's, an amp, and a box for $100 dollars. I know this may sound like a stupid question, but is there anyway to find out if they are dual 2 or 4 ohm voice coils. I don't have the sellers number anymore, and they came with no owners manual.

I am guessing it should say on the magnet. Not sure what the format will look like, but it should say somewhere on there (may be something like P2D2 for P2 sub and dual 4 ohm coils).

it should say on the bottom of the magnet, just look over the sub and you should find your answer

If it doesn't say, use a DMM and find the DCR of each coil. Round that value up to the closest multiple of 2 and that should be the nominal impedance.
