I own an Ampeg SVT4, and I'm connecting it to a 410 (900W) at 8 ohm. I allways use it monobridge-mode. So I doubt between these two options: -Buy an 810, then I'll take the max. power of the amp with just one cab and in monobridge mode. My back will not appreciate that. -Buy another 410 or a 412 (it would be 8 ohm) and combine it with the other 410 I already have. But, how do I combine it to take max. wattage of the SVT? -If I connect one cab to amp A and the other to amp B I'll get 300 W per channel. I Need/WANT more wattage for me. -How do I connect both cabs so that I can run the amp in momobridge mode. Then I could get 1200 W in to two cabs, wich is the max. wattage of the SVT. Parallel? Or maybe pluggin both cabs, each one to an amp, and using the mono-bridge option? Will that work? Is 410 and 412 (two cabs) a good configuration? Thanks folks!!
