Sub reads 131 ohm?!?!?!?!?1

[Jager 10+ year member]

So my DMM is telling me my FI BTL 15 is wired to 131 ohm.... I kept the DMM on the same setting and tried a normal infinity kappa door speaker and it read 2.9 ohm... im starting to feel like i dont know what im doing anymore.

my first thought was you simply have it on the wrong unit setting, but if the infinity read correctly who knows?

What kind of meter are you using? If its one of those ones you can get for free at harbor freight tools, throw it away, those are no where near accurate.

mine sh it the bed recently and was giving crazy numbers like that, turns out there was moisture inside that corroded the internal parts.

i pulled the sub out of the box and turns out my negatives came undone from the bolt running through the box, so it was reading the two postives wired together only, no negative. put the dmm in both sets of termionals and both sets read 2.0 still kinda confused on the high number though...

maybe it's reading 1.31.........not 131 lol

thats what i was thinking.

no it wasn't 1.31. i kept it on same setting and tested an infinity speaker and it read 2.9. not 290 lol but either way problem solved got it all wired back together and life is good.

when I blew my dd clipping like a mofo it read 139 ohms of resistance and 1 on the other coil if the sub is playing and gets warm the resistance goes up.

It doesn't have all the bells and whistles, but I have used my cheapo harbor freight one and my Fluke 87V at the same time with almost identical readings
