1500 watts RMS @ 2 ohms 750 watts RMS @ 4 ohms NOT 1 ohm stable. Most likely underated like most kicker products. I would say its true out put is closer to 1650 watts or more.
im gonna run an ava 15 off of that amp at 4 ohms ... and if i decide i want another one ... ill have a 2 ohm load ... which will power to 2 of them perfectly
