I'm trying to set up a pair of pipedreams with their subwoofers, but I can find no documentation online about them, so finding an adequate amp for them is very hard.IIRC, the subs are built to be operating below their resonance, so the crossover is EQ'd to give a boost of 6dB/octave. So you need a **lot** of power- a Carver 1000 watt amp (as the sub amp) I heard with them was clearly straining.
If it were me I'd go with a different sub.
