the subwoofer i drive with a yamaha dd rxv795 amplifier. (85wRMS x 2)Drives it quite nicely...the sub can run 2 pairs of satelite speakers.. The bose speakers i do not use because they're not in cabinets..but they are rated at 480wRMS/ 802 speaker cabinet so they can take a bashing...ive had them all tested, and they work to full potential.
