I'm working out the design for a custom 4x10 and 1x18 and I'm having a terrible time trying to figure out how to wire the damn thing. The cabinet is going to be an 8x10 fridge size with seperate chambers for the 10s and 18. I'd like to wire the cabinet with 3 inputs: 1) HIGH -> signal into the 10s 2) LOW -> signal into the 18 (for crossover purposes) 3) FULLRANGE -> one signal drives the whole thing (10 & 18 - for when I'd rather not lug around a huge amp) Is this doable? Has anyone ever pulled something like this off? I'm sure it's possible but I've been doing a bit of testing and I can't figure out a circuit to do this. Suggestions?
