you'll need a lot more RMS power then that to damage your subs buddy. Plus if you set your gains right with a digital multi-meter, you wont damage your subs no matter how much your overpowering them. If anything, these cheap amps might not even give enough power to get the full effect out of the subs and you might end up turning up the gain or volume too much and end up clipping the amps.
seriously man just let your budget grow and get a decent 1k rms monoblock amp, take it from guys who've been through it and wasted their money going up in quality in small notches, you'll be wasting a lot more money then your saving.
