Query: bad

my friend was using this amp on his two 10" square kickers and it worked fine but by the time i hooked it up on my rockford fosgate which are two 12" p3 the amp worked for about 5min then went bad it couldnt handle the rms and the watts so the amp went bad and made my system sound bad so this is good amp for smalls low power subs.
