happs subi Posted March 23, 2018 Report Share Posted March 23, 2018 From what i have seen most people wire 2 dual voice 4 ohm subs like in the first picture to get 1 ohm. 2 wires coming from 1 sub going to the amp. was wondering what would be the outcome of the two other pictures? with 1 neg from 1 sub, pos from the other sub? or 1 pos and 1 neg from 1 sub, and 1 pos 1 neg from the other going to the same amp?

happs subi Posted March 24, 2018 Author Report Share Posted March 24, 2018 Google told me to do the first configuration. I'm just curious what the other two would do. I don't really understand how crossing all these wires lowers the impedence. Link to comment Share on other sites More sharing options...
alex912005 Posted March 24, 2018 Report Share Posted March 24, 2018 First one is voice coils in parallel / subs in parallel and gives you a final impedance of 1 ohm. Second one is the same thing, only you are getting the positive from a different place, but since they are all connected to each other it's the same as no. 1. Third one is the same thing again, only with 2 runs of positive and negative (which you don't need). Your options are these: 1. voice coils in parallel / subs in parallel -> 1 ohm (parallel is positive to positive and negative to negative; series is positive to negative and the other positive to the other negative) 2. voice coils wired in series / subs wired in parallel -> 4 ohm 3. this would be everything wired in series which would give you a 16 ohm final impedance. You don't need that. My Build Log Link to comment Share on other sites More sharing options...
