This amp is hands down a beast! Not to mention an awesome price when you buy from here. I bought 2 of these amps earlier this year and they were both wayy under rated, it says 1500 but both of my birth-sheets says around 1900 watts @ 1 ohm. I have both amps on (2) 15" Sundown Audio Z subs and they freakin POUND. Just make sure you have the electrical in your vehicle to power these amps since they are constant power.
