determining resistance
#1
i ust want to make sure my multi meter is right, or if i am doing it right....i have 2 dual 4 ohm subs, and if i connect all v/c's in parallel, i get a reading of 1.4 ohms, is this right, and if i pull one of the v/c's out of the equation i get 1.9 ohms, does any one have any input on this?

Dukk is rigth.
Impedance will change with frequncy and will vastly range. Yes you can have up to 50ohms and above once a driver is loaded into an enclosure.
I myself use a Linear X meter card and built the "impedance cable" and test drivers wonce installed. It gives me a freq graph and shows impedance at cross the bad I specify.
But yes you can do the multimeter thing, but that only gives you a very narrow window of what is really going on.
