Amplifier for distributed bass array

Hello all

I have 4 Dayton Audio RSS210HF-4 8" subwoofers I'm looking at putting in a distributed bass array for a 2 channel setup. Room is 13x13x8. Subs are 4ohm single coil and 280 watts rms each. Enclosures are sealed. MiniDSP will be controlling the subs. Amp will be strictly powering the subs. 

I've looked at Dayton Audio's subwoofer amplifiers like the sa-1000 but I won't be needing any of the onboard sub controls due to the miniDSP. Dayton makes a dsp amp but again same thing. How much power would I need to get those subs sounding best? I'm not looking for high spl levels as most of my music is older stuff. But I want to be sure that the subs are moving properly from not being underpowered. I'm open to stereo or multi channel amps but want to keep it to one amp powering all 4 subs. Used or new doesn't matter. $1000 budget. Any beefy amp suggestions for this setup?

Thanks!

Maybe some AIYAMA A07s?
And the wall plug larger power supply?

You would need 2 for 4 channels and the AIYAMA go pretty high in wattage, but the heat could load up if it is slamming for a long time.

My daughter just put one in to feed some Sony bookshelf speakers.

They seem like they a not bad for a blue collar amp, but I have not heard them except for a short video I got sent.
The specs are like some 80+ dB SNR… So there are better and there are cheaper, but nothing at that SNR is that is as good and cheaper, nor better at the same price. You need to go to Topping PA3s, and the price doubles and the wattage drops. They would have been better for a booked shelf speaker, but not for a small sub (IME)

A few years back I started using Behringer 6 and 12K amps along with DCX2496. I've never looked back. I've tried a few amps too. :-) 12K are almost 30 pound of class Ds. #10 wire inside the amp with breakers, not stick fuses. ++ for me.

Dear @blue_collar_audio_guy  : I don't have experiences with amps to handled those four stand alone woofers.

I said woofers when you posted and mentioned subwoofers that those units in rality are not. In the best condition could go down to 30hz +,- 3db.

 

Anyway, good luck with your amp hunt.

 

Regards and enjoy the MUSIC NOT DISTORTIONS,

If it were me I'd go with something very simple, if I 100% wanted to keep the DSP out of the subwoofer:
