Subwoofer Not Giving ANY OHM Reading on DMM

[rickyfromthe407]

I was installing 4 DVC 4 OHM Subs, I got a off reading of 8ohm at the end of the speaker wire. I started measuring the OHMs reading on them. I am getting a solid 4ohm reading from one of the voice coils, but for the other voice coil im getting NOTHING. It shows no connectivity.

ANY IDEAS? I would think with a blown voice coil/sub i would be getting atleast something?

New Voice Coil?

I'm pretty sure its because of a blown voice coil. Don't quote me on that though

Open coil. Prob. done for on your coil.

Cool...Looks like ill be looking for a repair. Do I need a full re-cone kit?

Damn bro sorry to hear that. I've blown voice coils but the huge amounts of smoke from the burning copper signaled me to turn off my amps. For example the 3rd (and last) type-R I blew (from lack of healthy voltage and clipping) had 1 voice coil @ 2ohm and the other voice coil @ 4ohm. Both coils were supposed to read 4ohm. I imagine if you aren't reading any resistance then they're fully melted *OR* your voltmeter went bad. Personally I haven't seen less than 1ohm reading on a blown voice coil so I'm not totally sure but it's worth a try to use another meter.

It could also be a broken tinsel lead.

I am going to have to closely examine the tinsel lead. Its about 2am over on the East cost in florida at a chilling (to me at least) 33degrees. Its too cold for my Florida blood to go back out to the car, worked from about 6pm-12pm in the damn cold weather. Not fun! LOL.

I was going to run up the sub to a shop about 20 minutes from me and see if they can have a look at it.

The subs are Memphis Mojo M3 10"s , the old orange basket model with the red, blue, and yellow emblem/dustcap. So theyre an older sub, but I prefer them over the newer memphis.

But I think If i need a recone kit it will be hard to find, because i need the original to match the other 3 subs! Hopefuly it is just resoldering the tinsel...

But to @DWZ that sucks man, luckily I didnt burn it up myself, must have came this way when I bought them a few months ago. Just now had time to install them replacing the kicker Comp 10"s.

We will see what the shop says tommorow... Hope its a simple, inexpensive fix. If not. Might have to reconsider a whole new system

yeah, vc sounds welded to me. ha but damn. 0! ive smoked a couple and they still end up around .2

[LT.Smoke]

Id definitely say its a blown coil or open tinsel lead...I just fried my Sa-8 awhile back and i got no reading from it either and its turned out to be coils are shot

Sorry to hear bout the bad run of luck bro... Happens to the best of us

New Voice Coil?

Its an open connection somewhere. Either the coil blew open or like has been said, a broken tinsel. If it were shorted you would get continuity or 0 ohms, but you would at least get a reading.
