If you put more amps to your sub will it hit harder?

yes say you have a 10" kicker sub that needs 250 watts to hit and you have a 1000 watt kicker amp you have to much power going into that sub so it will hit harder. BUT if you but more subs and your amp has a few channels you can send the right amount of power to the subs without risking damage. i have 2 12"kickers with a 1000 watt amp so i have to much power but my subs sound amazing so do what you want most subs are $80-180 HAVE FUN
