So how would I hook these suckers up so that it will be stable? One sub per amp.

Thanks,

Parker2 amps and 2 subs. How do I hook them up?
Easy... one sub per amp, like you said. Each sub is dual voice coil, wire the two voice coils in series, to get 4 ohms per sub. Connect one series-wired sub to each amp, bridged, and you'll get 460 watts RMS to each sub, well within the sub's 500 watt recomended max (Ignore the peak rating, it's meaningless)



Here's a diagram how to wire subs in series....
