i know my mark anthony piece is not near what its rated becouse i hook my 3 jl 12's to my buddies amp and its just a pioneer from a pon shop thing and they hit twice as hard as i've ever heard them hit as a matter of fact i got told to turb it down and that was the first time ever i was impressed so i know for sure that i need a good amp i know pioneer isn't the best by any means but it was a deffinate improvement over this mark anthony thing.
