sony always lies on there watt outputs, there never what they say lol. i purchased a 1200watt amp from them to power my 2 15's, couldent handle them. i returned and and got a 2nd insignia package(the one with the 2 subs and amp) only got it cuz i need the amp,there wicked cheap but the only amps that could powere 15's. i haveboth amps runing each sub seperately. there only rated at 360watts to and if you look at the "1200watt" sony no comparison.
