You will not ruin anything with this setup, but I don't think it will be as loud as you're thinking it will be.
The subs are 4ohm each, wired in parallel that will be 2ohm to the amp.
The amp is only rated as 500 watt into 2 ohm, you need to ignore "peak" power numbers they are completely worthless.
Given the size and apparent quality of the amp i'm really doubting the 500 watt number as well.
The wattage numbers don't need to line up between equipment, you just need to make sure never to push anything to hard. The only thing you need to make sure of is that the load on the amplifier is within spec. In this case you'll be giving it a 2ohm load which it will be happy with.
