i have a 125.2 sundown for sale and it a monster i will do 170 shipped and i always like to have more than the reccomened rms so it there if needed if it clean power it should not hurt the speakers if your clipping it cause you dont have enough power so your turning it up to far to make the speakers loud than it worse than overpowering them but i have 3000 rms on tap for my highs lol ftw
