A cable question, sort of...

Thank you, Kijanki.  I usually prefer to let my posts speak for themselves, but since the question has been raised my background is as follows:

BS in Electrical Engineering, Columbia University
MS in Electrical Engineering, Rensselaer Polytechnic Institute
JD (Law Degree), University of Connecticut
Licensed Attorney and Patent Attorney

33 years experience designing and managing design of analog, digital, A/D converter, and D/A converter circuits for defense electronics, primarily airborne radar systems.

Kijanki is correct that coiling a cable in which the + and - conductors are twisted together or at least bundled together closely will not increase inductance to any significant degree. But **even if** it did so it still wouldn’t matter because the impedance presented by an inductance is directly proportional to frequency, and under any reasonable circumstances that impedance will be insignificant at the deep bass frequencies that are reproduced by the sub. And **even if** it is not measurably insignificant, it will be totally insignificant relative to the input impedance of the sub’s amplifier, which is very high as Miller indicated, and therefore it still wouldn’t make any difference.

Also, any slight increase in capacitance that may result from coiling won’t matter either at deep bass frequencies, and unless it is extremely high, and the amplifier is extremely sensitive to load capacitance it won’t affect the signals the amp is providing to the main speakers either. And of course the resistance of the cable won’t be affected by coiling.
