Just a little constructive criticism... only way to get better is to keep making videos and know are mistakes. Keep on keeping on.

If I may add a little advice, flip the subwoofer upright to test. It effects the reading drastically having pressure on the subwoofer. Another thing, on a 4 ohm DVC sub reading 3 ohm doesn’t mean anything is wrong with the coil, it has no load to it so it’s normal to read low, plus being upside down. If the coil was bad the ohm would jump all over the place and not read a steady number, or read like your second coil and read next to nothing. Thanks. 👍

so i have dual vented 12 inch MTX audio subs, with the amp set. it is 1000 watt amp but since i blew one of my subs it keeps going into safety mode when the bass is too loud. If i replace the blown subwoofer will the safety mode feature turn off? or is it permanent? asking because I dont want to buy another 100 dollar subwoofer if it wont work, thanks.

Only issue with the way u did this is u should have ur sub flipped upside down (from the way you checked it it should be magnet on table speaker / dust cap facing up) to check the coil resistance, but I checking for bad coils not sure if it matters or not but to get an accurate reading you should have it flipped and no air like a fan blowing on it to get a reading correctly cuz if u push on the speaker when meter is connected that meter is gonna go all over the place!

@kilgoretrout4461

No, it’s perfectly fine. No speakers ohm rating is actually specific to an exact number. If it’s rated at 8 ohms, anywhere near to 8 ohms is perfectly fine 7 ohms is fine, 9 ohms is fine. His claim that if it reads anything other than exact to 4 ohm, except maybe 3.9 ohms, is 100% pure bullshit. He is just Ill informed. Impedance, or resistance, isn’t a static thing. The moment that the speaker receives a signal, ie the moment that voice coil moves the slightest amount, the resistance is going to change wildly. His voice coil reading 3.3 is perfectly healthy. It’s not on its way out, there absolutely nothing wrong with it.

Hey there buddy. That first voice coil is probably just fine. Flip it upright, hold it still, and I bet it reads 3.5 - 3.7 ohms. Which is the what a 4 ohm speaker should show. Also, I don't think your words "about to go" or "almost bad" mean anything here. There's not a spectrum from 4 ohms to zero that a speaker will follow as it goes bad. It will read 3.5 to 4 ohm (good) until it doesn't (bad). It won't spend any time in between.

When measuring resistance it's 20-35 percent lower then the actual impedance. Not only that, the resistance will change once the speaker is hooked up and in a box.

All kinds of things wrong here. The sub being upside down affects impedance readings. Also, a multimeter reading resistance in Ohms on a speaker is usually off by about 25%, which means on a 4ohm speaker, a 3ohm reading should be expected. Certainly, it appears ONE of the voice coils is failing, but the one you think is 'about to fail' that's reading 3 ohms, that one is fine.

@@starmc26 If the flexible surround is touching the table and pushing the cone in, it will change the impedance. Hook one up and move the cone up and down while you watch the meter. That's how speakers work. Changing the current changes the electric field that reacts to the magnet. Manually moving the cone has the reverse effect of changing the ohm load.

i need your help because I'm dumb as F about car audio, can't figure this out... Im sure i have blown one of my twelve inch subs, but it passes all of the so called "blown-sub-tests" to check if its actually blown out. I think its technically bottoming-out but again I'M NEW TO THIS. So...The fuk'd up subwoofer does produce bass, & at a comparable level to the other sub in my SUV.. The problem is that unlike a blown sub that distorts bass (I've blown subs before & know how they sound) blown-subs make that muffled rattle where bass should be heard . Instead my failing subwoofer makes low & mid level bass just fine until the bass really hits; then it makes a terrible "Thwack!" Slapping sound. The slap doesnt reverberate or rattle. Just one sharp crack every time the beat booms. Some problems with subs are fixable & other's spell the end for the speaker; but NONE of the youtube vids or car-audio websites i have checked address this... & believe me I've searched The sub glides smoothly up & down within range when pressure is applied. No scratching, clicking or popping sounds come from the sub when I gently push it up & down... Sorry for the lengthy question but I'm trying to provide needed info to solve the problem. Do you know whats wrong? I dont know the impedance or ohms, just that its a 4-ch. 1,200 watt amp pushing two 12" subs. I traded a Hdtv for the system, then simply paid a shop to install it. Yes im a dummy; please help me solve this. Thanks

Another thing he doesn't mention, is to make sure you are running fresh batteries on your tool, or else it will also give you a false reading.
