marketing craps.... they say can is when you bridge it it will play low frequency only kua... dun expect much if you connect it to a sub directly...

not really... if you use normal mid-woofer like 6", 6x9 mayb can play if the speaker can handle them... if you wan it to play sub woofer then need a amp already.... cuz normally a sub will need at least 200Wrms to play... there is no HU in the world tht can give out tht much power i think...
