One thought here. For that much power, are you sure you want to put it all into 2 amps? If you think about it you do buy fewer amps but what if one blows? You need to buy another huge amp. If you had like 10 2000w amps, you'd have to shell out a lot less money if you blow one. I'd imagine that one of those 10,000w amps is more expensive than a few 2000w amps. I may be totally wrong but that's what I would think. Easy for replacement especially because you are going SPL and since you are going all out you see them blow stuff all the time.
