adreano17 Posted August 5, 2012 Report Share Posted August 5, 2012 I have 2 L7s DVC 4 ohm. Checked the resistance on the series and it reads 1.5 ohm. I wired for 1 ohm. Is this normal?

adreano17 Posted August 5, 2012 Author Report Share Posted August 5, 2012 is 1.5 after you wired them in parallel? no, SERIES.

Tarball Posted August 5, 2012 Report Share Posted August 5, 2012 is 1.5 after you wired them in parallel? no, SERIES. well, something isnt right. what is your ohm reading per coil? series should increase the resistance not lower it.

Guest Posted August 5, 2012 Report Share Posted August 5, 2012 did you do this? because thats the only series/parallel you can do. unless you did just series, which means you'd get like 16 ohms. your wiring is fucked up somehow, or you're using the wrong wiring terms Quote Link to comment Share on other sites More sharing options...

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?? did you do this? because thats the only series/parallel you can do. unless you did just series, which means you'd get like 16 ohms. your wiring is fucked up somehow, or you're using the wrong wiring terms 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.

LMAO sorry for the confusion between the 2. It does read. .5 for when the 2 are touched. I just changed the batteries on the damn thing, and need to recalibrate it (kind of suspected). Thanks everyone for the help.

CHEVY4X4BLAZER Posted August 5, 2012 Report Share Posted August 5, 2012 Glad you figured out the resistance issue. Do you understand the difference between series wiring and parallel wiring? Quote Link to comment Share on other sites More sharing options...
