Hi Rich,

The insane amp stack (2 x ADA1500-1 and 4 x ADA1500-2) is really for one application, the dance party. There just seems to be no end to everyone wanting to progressively keep turning the system up in direct relationship to the bar getting drained. But this application aside, something like a combination of an ADA1500-2 for the LF sections and an ADA1250-8 for the rest sounds like a smart combination. It saves money compared to two ADA1500-5s and you can still run balanced everywhere if you want. As to how much power is needed for the mids and tweeters compared to the bass it is tough to nail down an exact number as the content plays a big role. But we do know that you want to avoid any clipping at all cost as just a minor amount taints the performance.
