Woofer Speakers: Bridge a Dual Voice Coil

Video Transcript

"Back again and now we are loading up what is called woofers. You see in front of me I have two lengths of wire and now this is just for demonstration purposes that this wire is this long. We have a dual voice coil woofer, two sets of voice coils. We have the terminal connection that goes to the box. We will be now bridging the woofer end series. Where it had one set of strip connections on that end and another set of strip connections here in a moment. We will be going positive to positive and again we are going to wind the wire together so that it has a good tight thread and then we will be going negative to negative, wire polarity again so that we can have a nice tight thread. Why are we doing this? Well we are doing this so that we can take the amended onload of the woofer and drop it down to desired onload so that we can extract more power from the woofer and the amplifier. Positive to positive, here negative to negative here. Now you are going to ask what are we doing with the bare end of wire that we have left? Well I'll show you. Again stripping, not saying I am the Michael Jordan of stripping wires but I've been doing this for a few years and more than likely you probably at home attempt to do it with these strippers and you'll just chop the wire off. I've done it many times myself, even when I am having an off day I do it, still after all these years. Again now that we have that end connected we will be going to the positive side of the driver like so, negative here. We will trace the wiring connection back and you are going to ask well where does this go? Well this goes into the box so we have a positive driver, one positive, positive, negative, negative. We have the connections and we have just taken a stool two om driver and reduced it to one om. Congratulations. You made this woofer capable of being loaded on your mono block or your standard AB class two channel AB and stereo configuration but more than likely the sub will not go into mono block."
