I've been reading GM's comments about stacking 511s, and would like to give it a try. How do I hook them up? Series? Parallel? Second crossover? Different crossover? I have pretty limited electrical skills, so I'd prefer to stay with a "plug and play" approach.

Currently I'm using A7s with GPA 515LFs, 809-8a crossovers and 511 horns with 808-8a drivers in a 3200 sf shop. I'd prefer not to bi-amp or use active crossovers.

Thanks in advance-
