no, SERIES.
well, something isnt right.
what is your ohm reading per coil?
series should increase the resistance not lower it.
All 4 VC measure ~4.4 ohms. I am using 10 ga speakerwire that has .5 ohm resistance when measured. I wonder if that extra ohmage is from the wire??
nah you can wire negative to negative, positive to positive: http://a248.e.akamai.net/pix.crutchfield.com/ca/learningcenter/car/subwoofer_wiring/2-DVC-4-ohm-mono-low-imp.jpg
series: 1 ohm.
That's wiring in parallel, not series. You might be seeing the resistance in the leads of the multimeter. Touch the leads together and see what it reads...if it reads about .5 then that's where the extra .5 is coming from, and means your actual load is only 1 ohm, not 1.5.
