Sub not reading resistance

[Awhitewookie]

Overview: (4) subs, each quad 1ohm coils wired to 1 ohm each. Then all wired to 1ohm final.

Subs were great but then I got a new job that requires me to drive a lot. So, I took everything out for the mpg's.

What was your exact resistance reading before the trouble?

Looks like your connection to the sub got broken or the coil broke/blew.

Like you said, I'd follow the path back to the coil and keep checking with the meter to see exactly where the break is.

Your meter leads are going to add ~0.3ohms or so to the measurement so you have to factor that in as well.

Oh I forgot to add: When I connect my final leads together and then measure the bottom terminal, it reads 1.8

Resistance before was all the exact same as in the video, but that bottom sub was reading

If the resistance was "exactly" the same as before the trouble then two things have changed.

You're not reading resistance at the bottom sub AND you're gaining it somewhere else.

If you remove a resistance from a system then the resulting value MUST change.

When you're down in the ~1ohm range, very small changes can have a big effect.

Check all the connections. You may want to measure each of the connecting wires to make sure they all read as they should.

I understand that, which is why I am so confused! I guess it is time to pull the subs and check it all out.

Was going to be my suggestion to pull the subs out and check each coil by it self

Yep, sometimes in situations like this its best to pull everything apart, measure everything separately and then reassemble piece by piece, measuring at each step.

That will for sure find your problem.
