What you need to do is find out what the RMS rating is for the subs at what ever the ohms are 2ohm, 4ohm, dual 4ohm, or dual 2ohm. There are other combinations but 4ohms is most common. Then you need to check the amps rating. Not the BS sticker on it that says its 1000watts. Find out what the actual RMS output is for 12-14 volts on the amp for what ever ohms you plan to run it at (example 2 ohms or 4 ohms). If the numbers match up then you are good.
