I just would like someone to verify something before I wire her up. I have a 4ohm DVC 12" sub. If I wire it in series, it will now be an 8ohm sub? And when I connect to my 2 channel amp, bridging it will then drop it back down to 4ohm? Or will it stay at 8ohm? And if the amp is stable at 4ohm briged mono... is it ok to put an 8ohm load on it?
