[QUOTE="98 SNAKE EATER, post: 8707265, member: 588245"] Not doubting you as I'm still rather clueless about this, but the switch on mine doesn't appear to have a resistor bank, just looks like an ordinary switch board with some really dinky lookin wires :unsure: [Img]https://i.postimg.cc/tqSw-tFRk/JBLStadium-Sub-19.jpg[/img] That being said, I just found this old Sonic video introducing an Infinity Kappa sub with SSI (I believe they share the same switching setup), but they claim to have a triple voice coil in order to switch from 2 to 4ohms 🧐 [MEDIA=youtube]RkIuYST9pJ4[/MEDIA] [/QUOTE]
