is this normal?

i wired my 2 dvc 1 ohm 12" re mx subs and meter reading is showing .5-.7..... shouldnt it read 1.0 ????

what does each woofer read individually? what does their coils read?

you worded that weird...

Sounds like you wired it wrong. Try again. After you take your meters resistance into accoutn I bet your down around .25 or something like that.

So you have two DVC subs, and each sub has two 1 ohm voice coils?

If I understand your question correctly....

All the coils in parallel ~0.25 ohms.

Each sub's coils connected in series and then the two subs combined in parallel ~1 ohm.

Each sub's coils connected in series and then the two subs connected in series ~4 ohms.

All that being said, there is bound to be some "play" in the numbers because a 1 ohm VC won't necessarily show as 1 ohm on an average DC meter. And most average meters aren't that precise at resistance levels that low. 0.25 ohms might as well be a metal paper clip for most electronic applications.

If you are in doubt. Read each coil individually. If they all are in the the same ball park, your subs are probably fine and your final load should be +/- 0.5 ohms of what you wire them for.

You are measuring resistance with your meter. Your subs are rated in impedence. The difference is "resistance" applies to a DC circuit. "Impedence" applies to an AC circuit. The same resistor will have a different value on an AC circuit vs DC. This is why people measure woofers and get a slightly different measurement with their meter.

1.0-1.2

i checked my pair of 10's and their reading 1.0 they are dvc 4 ohm with the same meter i will take a pic and post it when i get home from work today....

This is precisely what I was about to type. Pay attention to these statements. This is your answer.

I'm not sure if read the OP right.

If you are checking just one sub then Ecrack and Mobile are correct. If you have both subs wired together then you need to rewire and check again.

i have both subs wired together but when i wired it to be a 4 ohm load it read 3.5-3.6 and also is it even possible to wire 2 dvc 1 ohm subs to a .5 load!!!! I WIRED IT ACCORDING TO THE12VOLT.COM

exactly, I can't believe some one actually posted that.

No it is not, but depending on your DMM it may appear to by wired like that lol. As for your reading you are just fine.

Thats about right for DC current on a 4ohm load. As far as .5 ohms on (2) dvc 1ohms, no. but .25 yes. (2) dvc 2ohms can do .5.
