Unfortunately, the amp won't power on from idling for years not being used in our Home Theater. Can be repaired or replace with external amp. The individual woofers are still selling for over $200 each, looking for best offer.

This monster has two 15-inch woofers; a Class D 600-watt (1,500 peak watt) power amplifier; in a 22-inch-high, 18-inch-wide and 24-inch-deep cabinet that weighs 120-pounds. Last time we used it it shook the entire house and could be heard at the neighbors
