    I get the whole 2 x 8 ohm speakers = 4 ohms combined. Now how does Accugrove wire a switch into their cab to switch between 4 and 8 ohms?

    Is there something I can go out and buy and rewire my cab? Anyone have any info on this and what needs to be done?

    Thanks ahead of time.

    No, you can't go out and buy a switch that will do that.

    A while back we were grilling Accugrove in a thread about how they do it and got nowhere...patented stuff I guess.

    I figured out a way to come close with two drivers with tapped voice coils, but it would be a totally custom thing.

    The easiest way to do this is with dual voice coil woofers. If each coil is 8 ohms you'd use 1 coil of each driver with the two drivers in parallel for 4 ohms, and both coils of each driver in series with the two drivers in parallel for 8 ohms, just to name one possibility. But you'd need custom built dual coil OEM woofers.
