You are completely correct! That is exactly the point of having a DVC subwoofer. Different wiring options! The only downfall to wiring only one voice coil is you have to run lower wattage to the subwoofer. Of course, there is an upside too. (already stated earlier by haemphyst) I knew guys that use to do this all the time when I was younger. (hook up only one voice coil of a DVC sub) They loved this new idea of subwoofers having dual voice coils. Don't know how it first started, but a very cool invention. So is the removable voice coil.... very sweet. Much cheaper too! ___________________________________ Do whatever makes you happy in life without diminishing the happiness of others
chronic2001 Posted August 29, 2012 Report Posted August 29, 2012 I believe hhr Ed posted a video about box rise and in it he mentioned you can run 1 coil off a DVc sub. IIRC he said it just couldn't handle as much power with 1 coil hooked up.

bkolfo4 Posted August 29, 2012 Report Posted August 29, 2012 You can use one coil, just cuts the power handling.

Jessica Posted August 29, 2012 Report Posted August 29, 2012 I think you may run into problems when you start to reach the power handling limits of the voice coil. What I mean is, say you have a dvc at 300rms per coil. You put 300rms into said coil, but the other see's no power. Now the suspension of the sub is designed to work with a certain motor force behind it. You are giving it half the motor force. But you are still throwing power at near the thermal limits of the voice coil. I think in that situation you may cause heat and distortion issues. I am probably completely wrong.

Jessica Posted August 29, 2012 Report Posted August 29, 2012 no need to apologize, lol. I just had some dvc many years ago and with one coil unhooked it distorted sooner than with two. But there are too many factors to ever figure why that happened.Probably just cheap subs and or amps. Rest in peace, walled 87 accord build log 03' Corolla build with AA Mayhem inside.
