sub impedance issue

[los33 10+ year member]

I just received a hdc3 12" dual 2 and wired it down to 1 ohm.

The wires coming from the cone were very long maybe 1 1/2 feet long or more.

so i wired it using RF 8 gauge ofc, but when i check the ohm reading i got 1.5 ohms.

Ive never had it only drop half a ohm before so could this be due to the long wires?

I plan to un-wire it today and check impedance on each coil to make sure they read near 2 ohms.

Mines the same way.

Mines the same way.

If thats how they are then how do we get a full on 1 ohm power?

after my box rise i probably will be at 1.8-2 ohms.

I need a new box, but its currently in a 3.4cu ft tuned @ 34hz.

Yea I'll buy yours and u can buy a dual 1 wire it to a half you might get .8 and well both be happy

Haha unless you pay how much i bought it for plus shipping

the subs only got 2 mins play time.

Hope you got a good deal ; p... but I don't have your answer, just reinsurance that your not the only one.

My guess is your meter is probably not good enough to read impedance that low with the precision you're looking for.

I do have a cheap *** meter...

Newwbie mistake :/... toched both pins and got .5 ohms resistance.. so sub fluctuates between 1-1.1 ohms.

Walmart :/ costed me 18$

scrap the walmart meter. atleast go to sears and get the $25 craftsman version

No worries mate, that cheap meter will be good for just about everything else you need it for. I own a $200 Fluke meter (work paid for it not me) but still keep a couple cheap $5 harbor freight meters lying around just because they're handy to have when I don't want to get the fluke out.
