Thanks for the input. 2x10, 1x15, and an ISP Bass Vector which is a 1x18+2x8. It's the ISP that's the SOB to get loaded up in a vehicle. It fits in my Leaf, but it's never fit in any sedan trunk I've ever seen. I usually only run with the 2x10 and 1x15 (or just the 2x10) if in a smaller venue. I only consider the ISP if I know I need a lot of on-stage sound. It's an edge case, but it does happen.
