That amplifier is only stable down to 2 ohms. You will need to wire the subwoofer in series in order to make a 4 ohm load for that amp.

Parallel = jumper from + to + and another from - to -. Series = jumper from one coil's (or Woofer's) + to the other coil's (or Woofer's) -. Then with the 2 other terminals ran to your amp. First diagram is parallel. Second diagram is Series. I did not look at your speakers, I have no idea if they are single or dual voice coil. Following is only and example to show difference between series and parallel. | Option 1 (parallel) = 1 ohm load
Voice coils wired in parallel
Recommended Amplifier: Stable at 1 ohm mono | 
| Option 2 (series) = 4 ohm load
Voice coils wired in series
Recommended Amplifier: Stable at 4, 2, or 1 ohm mono |  |

The amp you have will be slightly under powering that speaker. With that being said the amp you have should be fine as you wouldent notice much of a difference if you got a bigger amp. That speaker is rated for 500 RMS and it will be seeing 300 RMS. The subwoofer is dual 2 ohm coils. So the wiring options you have are either 1 ohm or 4 ohms. You have to run your speaker at a 4 ohm load because your amp is not stable at a 1 ohm load. Follow the diagram option 2 that i am an idiot has posted. Then measure the resistance with a dmm to make sure you wired it correctly. If wired correctly you should get a reading close to 4 ohms.

My speaker can hold 500rms in 1 ohm and in 4 ohm?

According to the Specs you posted, the amp will produce 300 watts into a 4 ohm load. It will produce 400 watts into a 2 ohm load. Your only choice is 4 ohms. It will put out 300 watts. So as stated earlier, I too think that the 500 watt woofer will be slightly underpowered.
EDIT: I wrote this after only reading the part of Ragsports saying it was underpowered. Then I went back and read his post. So I guess the So as stated earlier should have been at the very beginning of my post. Sorry

Isn't it a difference between 500rms at 4ohm and 500rms at 1ohm? Are you sure my sub can handle 500rms at 4ohm? (Maybe ill buy another amp)

Your speaker can handle 250 watts per voice coil. It has no Idea how you wire it up. You do not need to buy a new amp, at least play it and see if it does what you want it to do. It is not a crime to underpower a speaker. It may be a Sin, but not a crime.
