Autotek SS1900.1
1000-Watts RMSx1 @4 ohms
1500-Watts RMSx1 @2 ohms
1900-Watts RMSx1 @1 ohm

Which one would be better to power my 2 15" XLs..dual 4 ohms....600 watts rms but i know they can take way more with ease....not sure if they could handle the Autotek though since i keep hearing that they actually put out around 2.3k watts.....but i guess i could always just keep the gain down....
