I'm getting to a point in my build where I have to decide on amps so I know how much space I need for them so I can finish my enclosure. I need something that does >1000w at 8ohm, the more the better. I have an area up to about 20"x20" to work with and all of the amps I've found that will do that much are too long. I have plenty of depth and can stack the amps if I need to so I've been looking at smaller amps that can be strapped. In my search I've come across these and while I know they're overrated, I'm wondering just by how much. If they only make 40% of their rated power that's still 1200w and I can get 2 for <$240 but I'd hate to waste the money if they can't even manage that.

There's also the Zapco ST amps

Or the Phoenix Gold

Ideally, I'd like to spend as little as possible but am willing to spend more if necessary. I like the PA because they're the cheapest option by quite a bit. I only really like the Zapco amps because they're small and I trust them to do close to rated power. I like the Phoenix Gold because I know a dealer and could probably get them for a similar price to the Zapco amps and if I went with them I could sell one of my Arc 1200.6 to buy a SX2 1200.6 and probably come out a few $ ahead and have matching amps. So my question is can I get away with being cheap or do I just bite the bullet and buy something with a decent reputation? Are there any other options I've missed?
