The reason for dual voice coil speakers is to give added flexibility
on the loads of the amp..letting one adjust let's say from 4 ohms to 2
ohms..and the same for dual 8 ohms coils you can switch from 8 to
4....but as for connecting each voice coil separatly...I'm not
sure...i know it's an absolute no-no in stereo configuration where
each channel is getting diffrent signal..that is obviuos..
