Ok, I looked up the specs of your amp. It puts out 300w at 2ohms to 1ch. This means you are supplying 150w to each of your subs. You will need to get a bigger amp. You need an amp that puts out 600w at 2ohm load.
Still assuming your subs are svc 4ohm.

the other problem, you paid way to much for that kit.

How bout you give us the numbers right from the sub. The site says 3oow for the pair, so 150w each....
that seems really low for subs
