I Got The Wrong Speaker

[jcarter1885 995]

you can buy one for $20-$25. No need to go crazy, but in this hobby you will need one. It's priceless.

x2, I havent looked back ever since I bought a DMM and it came in handy (thought I would only use it once but it gets plenty of use). Didnt think I needed one but yeah you will even if it is just to measure your battery, alternator, speakers, set your amp up, etc.

I understand that : you ordered right , you paid and got a wrong item.

Now they tell you to go mesure with a DMM !

It's a pitty, but We're all humans and make mistakes.

Send a message to IA, they will take care of you, for sure !!!

I have no access or cash to use one, it would be a lot simpler if I just knew it was labeled wrong or right. How much is a DMM and where to I get one?

You can get one at Wal-Mart for like $15.

And on top of that if a 200 dollar subwoofer is in your budget but you cant afford $15 for a DMM then something is wrong here. Just my .02. Not trying to judge. Just stating an observation.

I don't have the money to check for someone's mistake, I'm not responsible for that.Note, I'm not mad... I just want to get everything installed already. No need to get hostile because I don't want to buy a DMM,its not a item I necessarily need.

If I took a poll I would imagine 98% of people would say they needed a DMM when it comes to Car Audio. Just putting that out there.

[keetykush 34]

Note, I said " necessarily needed" meaning not that I wouldn't want one in the future. Its not really another item I feel the absolute need for at the time.

Well you kind of do need one right now. I know my DMM has been useful more times than I can count. Best 20 bucks I ever spent.

How do you know it's the wrong woofer? It probably shipped in the wrong box, they could have re-used a box.

x2, regardless of what my box and sub (or speakers) says if it has markings on it I still measure it with the DMM first.

[shizzzon 461]

let's look at all the uses a $20 item can do and see why people don't need them..

They can determine if you received the right speaker.

They can determine if the coils are damaged.

They can determine if a battery is discharged and needs charging.

They can determine if your voltage regulator is working properly.

They can determine if any power wire runs are shorted to ground by accident.

They can determine if a fuse is good or not.

They can help in tuning an amp to a certain extent.

They can help measure output of an amp but requires more than just a DMM.

They can help measure voltage drop issues.

They can help find resistance issues with voltage drop from the front to the rear of the car so you can isolate where the problem is occurring.

They can help measure voltage levels inside the house and frequency to determine if you have a faulty outlet or wiring in the house.

So with these common problems... you are probably right.. you don't need one.

[stocks 2]

if you do contact them, ia will probably want you to check the coil readings with a dmm..

[jcarter1885 995]

Go to Wal-mart buy the cheapest one or it really doesnt matter, use it and take it back if you really dont want to keep it. This may save you in shipping cost if it is the right sub after all, so the only thing you will be wasting is gas to Wal-mart at the end of the day.

Good post Shizzon. +1.

x2, now I know all of the uses for a DMM for my needs.

[viper167 1]

im going to have to agree that you need one DMM.

i dont even do that mush car audio , and i have 3 of them !

in my opinion if you own a car, you should have a DMM.

not only that put you can use a DMM to check something as simple as a AA Batt. i know i have before!

[keetykush 34]

My father supposedly has one, so I'll just have to see how it goes.

[shizzzon 461]

i gotta buy a new dmm like every few months... It seems Sears' dmms under $50 are crap... either that or i'm too loud since i keep em all in the car.

only i have problems with reliability though.. it's prob the 155db+, lol

My harbor freight special works perfectly and it's pure Chinese shit. You are spending too much Shizz.

Craftsman FTW!

[keetykush 34]

Ironically, the one I got isn't working... the readings are going all crazy( unless I'm doing something wrong).

[shizzzon 461]

the ones i buy are usually in the $25-30 range. the last one i bought, soon as i got home, noticed the vAC function doesnt even work... figures... I ALWAYS get the screwed up dmms...

I have another one that can't read resistance or vDC... then i got a free one that doesnt read any volts or resistance... Kinda makes me wonder if Rd Audio is behind the engineering

User error.

You should be using the DC Resistance function.

[keetykush 34]

I used every setting on the DMM and it was very inconsistent, what should the reading typically be for a d2 and a d4... on each side?

You need to be using the ohm symbol. A D2 will read ~1.4 ohms per coil, and a D4 will read ~2.4 ohms per coil.
