You definitely need a bigger amp capable of around 1000 watts at 1 ohm
That amp is a single channel and is only stable down to 2 ohms.
You CAN wire up all four subs to that amp but it won't be that loud at all...and you'll prolly clip the amp. Wired in parallel series each sub would be getting about 37.5 watts a piece.
you have the wrong specs for that amp.... here are the specs to that amp

Two 4 ohm subs in a parallel circuit will net a 2 ohm load. This is safe to operate on that amp as far as the load goes. As far as the power ouput goes, my bet is that this amp really puts out 300w rms into 2 ohm and less into 4 ohm. Even if it puts out more power into 2 ohms, you will still be alright with the amp to sub match. Now, the one thing to be carefull about is that gain control. Set it wrong and you are going to do the crispy critter to the subs. Abuse the subs, they will die.

you do not need a 1000w sub amp. 300 - 400w would be perfect.
2 subs, right?
