two 4 ohm subs equal 1.8 ohms????

based on the info i just gave about my amp and subs, and the 1.8 ohm reading, can u guys determine if my subs are cual or single coil?

no, but i don't know if kicker ever made single coil L7's or not

teh yea, i have AIM.... I think theres 2 sets of speaker terminals not sure though

and if they are dual coil we still have no way of knowing if they are 4 ohm or 2 ohm unless kicker never made 2 ohm coils

i know my subs are 4 ohm subs for sure... i just dont know if they are dual coil or single coil

do you have the box they came in?

Just because a sub is labeled as "dual 2 ohm" or whatever doesn't necessarily mean that each coils is exactly 2 ohms. Sometimes the coils can be off a few tenths of an ohm from what they're labeled as. You may also need to take in consideration that the DMM could slightly be off because the DMM has its own resistance once it is included into the circuit. Touch the leads of the meter together and subtract that value from the measured value that you read from the coils.

Ah the world of electronics. Never exact //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

As said above, we need more information to tell you what you have them wired to.

NOMINAL impedence is just that. Since the ACTUAL impedance of a speaker varies with frequency mfg's try to specify an impedance that will represent what an amp will actually see averaged throughout the speakers usable frequency range.

I've never seen a speaker with an at rest DC resistance that equals its nominal impedance, and there's no reason they should be equal, but they're generally pretty close.

That being said - I'm sure the L7's in question are DVC's. The question is by 4 ohms do you mean they're dvc 4's, or dvc 2's (which are 4 ohms with coils in series).

It stands to reason they are dvc 2's only because I wouldn't expect a pair of dvc's wired for 1 ohm to have a DCR of 1.8, that sounds more like a pair of dvc 2's wired for 2.

at this point...who knows?
