You need to take the power delivery to your system into account. If your system is on (1) 15 or 20 amp circuit, you'll need another (as in dedicated) line if you want (2) subs like the Fathom 113s - they are 2500 watts each.
I sold my Fathom 112 to a friend and went to (2) James EMB-1200s, because I wanted stereo subs without adding a dedicated line.
