If that is what he was doing, he could've put it on a meter to either check impedance or continuity. No need to connect wires or bring a battery over. For that matter, he could've done the exact same thing with any battery.
@@abusyguy1757 I'm pretty sure he's checking the polarity of the coils. Most people would use a 9v battery... If the speaker moves out you have it wired in phase and if it moves down its 180° out of phase.
He tested to see if the positive and negative on the subwoofer were wired correctly. I bet if he changed the positive on the negative on the battery and the negative on the subwoofer to the positive on the battery the subwoofer would move down instead of up. He also was seeing if each coil worked seem how it is a dual voice coil and has 2 voice coils.

I was affiliated with a sales and installation shop in late 90s early 00s.

After several back and forths with the rep we delt with at manufacturer, ultimately explaining we wasn't going to continue selling their products if the shop had to eat failures. The rep told us to " cut a lamp cord and hook to the equipment and plug it in " which we did pretty regularly and was pretty entertaining. The company was KOVE
Back before wiring harness where made for every make and model under the sun, wiring an aftermarket head unit meant u had to literally figure out what wires went to what speaker from the back of the radio. So we used to use a 9v battery and tap the wires to first figure out which was which but also + and -
I just pulled the door panel off and hmm these color wires here oh must be the same ones here then touched a 9v and watched it myself because nobody ever wanted to help the guy do his stuff and learn. So I just charged them the same price as the radio plus 10% to install it. Wasn't much but bought the beer that helped me install it lol
I remember these days !!! You'd find your power wire your ground and plug the antenna in. Then you'd touch the speaker wires til you heard them where I wanted them. Half the time I'd just hook the speakers up randomly. Whatever. Lol
@@Coted1988I've installed at least 60 radios like that. Started out installing systems i in my own cars and yes I burnt a few channels out in the process of learning but wasn't long before all my friends, family members started coming to me.

All car have a 12v battery, that's what powers the head unit and the amplifier. It is a lot easier if you use a 9v because the leads on the speaker basket are usually close together and you can just touch the battery to the connections. No need to be fumbling with the wires second guessing yourself thinking you crossed the wires somewhere down the line.
checking polarity making sure both coils matched up. Having a dual voice coil sub with one coil hooked up with reversed polarity to the other one. will cause the sub to not move and build a ton of heat.
No it's checking the positive and negative to make sure he wires it right. If it's positive the speaker will push out, if it's negative the speaker cone will suck in. Very easy way to do it. You can use a AA on a small speaker, not tweeters. 9v. works well with most full range speakers. Big batteries for big subs.
Polarity check ✔️ If you're looking for a quick, free way to test subwoofer polarity, you can do it using the following method: Mean subwoofer plus (+) minus (-) which wire is correct
Also handy for figuring out what wires go where. On hime theater or in your car to the deck. Recommend using a bit smaller battery for most of them. You can use a c or d cell scratch the battery with the wires and listen for the static...
@@aninjacalledshank2278actually 12 volt battery is just fine due to the fact that even most entry level subs even in the 6 and 1/2-in range see more voltage. But you don't want to hold it on there because that would be equivalent of clipping

We use to plug them in to aminiasc. Scope at .3 amp. At 100 volt at 60 cycles per min they'll dance then they'll light up under the voice coil cap glowing for a bit as the get much louder.. then smoke and a big lightning bolt would come out from under the voice coil cap... Rockford Fosegate would last the longest giving quite a long show with long time smoke before the lightning bolt.
9v battery does the same thing and is easier on the coil…small speakers in a lot of cases the speaker connectors are spaced so jumper wires are not necessary
To all the 120v crowd....you do realize that's 120v AC and not DC right. Do you know the difference??? AC voltage applied results in the woofer moving in and out like normal. DC voltage applied results in the coil becoming an inductive heating element. If you still don't understand, please get some education before commenting.
@@effenffor one it's not dual channel it's dual coil. For two that is not why he drops the lead and picks up the other lead for it to be so obvious.

Reminds me of old days working on golf course.People would be jealous of headunit and speakerbox booming,wired to battery on golf cart plus mine was not governed ,turned all the way up .Was real fast .
Black wire is almost always the negative, thats pretty common knowledge, i thought. He must be testing function before buying/selling, not testing polarity. My thoughts about it anyway.
U can do this test with any subwoofer to check polarity or for a short in a coil ..Also good to know your amplifer actually supplies AC not DC current to your subwoofer it takes 12 volt DC in for power and converts that to ac out to your subwoofer
@@mikga45 Car speakers need a lot of power, typically at least 20 volts of peak-to-peak voltage, which allows them to reach 100 watts. Most amplifiers configure this with a power supply that converts the car's DC (Direct Current) method to AC (Alternating Current) since that is what's used to drive car speakers.
All he is doing is what’s referred to as a “pop” test and Polarity check, they most likely reckoned the sub and was doing a quick check to make sure it was good
So reckoned speakers are still a thing? I need to see if anything is available for my old Memphis 12s. Really only need to do one, but if i had the supplies, id do both just because the dang things are probably 20 years old. i only want to save them because they have been super good to me over the years.

Polarity Testing. Can do this test with a 1.5v battery on smaller speakers. Correct polarity, matching battery + and -, pushes out/up and reverse is the opposite.
Use a 9v battery for the small speakers. But yes I do this with subs I wire dual 2ohm subs to 4ohm and just plug them in a 120v outlet for break in at a full 3600w
The easiest way to test your polarity to make sure you have the speaker wired right which can still be wrong it's only right if you have it wired to the right ohms
He's actually just checking the polarity of the plug-ins nothing fancy just a quick way to check positive and negative sub goes down its backwards if it goes up it connected riight👍
he is not testing something he just confirming witch one is positive terminal and witch one is negative for better sound output. if you put wrong terminal in battery the speaker paper goes inside if its ok than its come upper side. its basoc funda. 🙂
When you touch the battery with the wires if positive and negative are in the correct position the subwoofer will push out. If it pushes in the positive and negative are reversed.

Right 👍
Well it doesn't work if the coil is loose since the rattling will mostly appear when playing music but it works great for polarity testing 😅
A sub this size is easily able to be plugged into a 120v wall outlet. A 9v won’t do much.
