Dayton Audio SPA500 500W Subwoofer Plate Amplifier
I have two 18" Dayton HO subs in 4cu/ft enclosures in a 1,800 sq/foot room with an open stairway. If I am using Dayton 500 watt plate amps on each, am I under powering them? Do I need the 1000 watt amps on each?
We recommend as much headroom as possible when dealing with subs, but as long as you are not clipping the amplifiers there is no need to upgrade the power.

I currently have 4 aura bass shakers powered from a Dayton 250 watt plate amp. I would like to increase the number of shakers to 8. Is there any reason that I could not power them all from one 500 watt Dayton so I don't have to split my LFE signal?
Eight shakers will have to be wired to 8 ohms, so you will only get ~250 watts from this amplifier but it is certainly possible. Getting a second SPA250 will save money and double power if you wire 4 shakers to each, so this might be your best bet. Splitting the LFE output will not negatively affect anything.

Hello, Is Z-Min 4 ohm or will this unit drive a 2 ohm load .....
This amplifier is not stable at 2 ohms. it is limited to 4 ohms or higher.

I see one answer that the sub-1500 would need modifications to the cabinet to fit. Any idea on ohms for the sub-1500 Is it two or 4 or 8 ohms. Thanks
The woofer in the Dayton SUB series subwoofers are 4 ohms.

Would this amp run 2 10” 4Ω Subwoofers with the Power Handling: 250W – 750W each? If so should I run them parallel or in series?
Yes it would but you would have to run them in series effectively halving the output from the amplifier (~250 watts total, 125 to each woofer). You might want to use the 1000 watt model which will provide about 250 watts RMS into each woofer wired to 8 ohms.
