solar0987 Posted May 4, 2016 Report Share Posted May 4, 2016 Ok long story short I ordered a used sub... It finally got here. Measured the coils using a dmm. First i touched both leads together to get the resistance of the leads. they registered .001 ohm. Then i put them on the voice coils. It read .001. So im led to believe the coils are blown.. Am i correct in assuming that? Link to comment Share on other sites More sharing options...
Triticum Agricolam Posted May 4, 2016 Report Share Posted May 4, 2016 Most likely. Do both coils measure .001 ohms?

Triticum Agricolam Posted May 4, 2016 Report Share Posted May 4, 2016 You can always do the pop test too. Take a 9v battery and briefly touch the terminals to the bindings posts of each of the coils, the cone should move.

Triticum Agricolam Posted May 4, 2016 Report Share Posted May 4, 2016 Yeah, that's not good. Try to the pop test and if the cone doesn't move for both coils they are definitely toast.

Ahmed Johnson Posted May 4, 2016 Report Share Posted May 4, 2016 not good bro. I just watched my buddy glue some leads that burnt off and sold them to somebody. I feel guilty, because I pointed to his problem instead of keeping my mouth shut. Link to comment Share on other sites More sharing options...
solar0987 Posted May 4, 2016 Author Report Share Posted May 4, 2016 So they move off the 9volt battery. Link to comment Share on other sites More sharing options...

solar0987 Posted May 4, 2016 Author Report Share Posted May 4, 2016 also tested the dmm against a couple batteries. 9 volt read 8.92, car battery read 12.4 resting<-- think thats right term for " nothing on " Link to comment Share on other sites More sharing options...
Triticum Agricolam Posted May 4, 2016 Report Share Posted May 4, 2016 Do you have your DMM set to read ohms, not volts? ETA: You might just want to take a picture of how you have your DMM set when you measured the coils and post it here.
