The Earthquake 10D woofer is a passive woofer, unpowered.
It comes with two five foot long heavy duty speaker cables (i.e. left and right channels). The item description doesn't say this. The installation doc doesn't make clear these are traditional left right inputs.
I connected them to the Bose SA-5 amp in parallel with the Bose 251's, noting polarity. Red is +.
The SA-5 drives the 10D and the 251's perfectly. There is no clipping or other evidence of overload at any volume.
The 10D is a very nice complement to the 251's... it fills in the bottom end quite naturally.
From a distance, it does indeed look like a rock.
