Hey Dante. Originally it could have been wired either each pair in parallel, then the 2 pairs in series (8 + 8 = 4, then 4 series with 4 =
or more likely (as I assume you changed as little of the wiring as you could) the 2 pairs each in series (as per your pic) then the 2 pairs in parallel (8 series 8 = 16, 16 + 16 =
, also most quad boxes seem to be wired this way.
If you go with this configuration, you can use one normal jack and one switching jack (like I posted re how I have one of my cabs), or use a switch
.
Depending on the amp(s) you want to use (and particularly if they have SS output stages eg MT100/200) a better wiring IMO (and as Harley suggested) is to parallel each pair (8 + 8 = 4) to get the most from the amp in stereo. Then series the 2 pairs (4 series 4 =
. So cab then is 8 ohms mono, 4 ohms per side stereo (which is what was asked for in a previous post). You could do it with a switch or 3 switching jacks. Noting that the SL (switch lugs) connect to the tip (+ve) when no jack inserted
