It would do fine on a 500 watt amp, as long as its decent quality and puts out the power. I loved the sound of it...but i upgraded to 2 12w6's. I wanted my wife to have this one, but she dont want subs in her new car.Good SQ sub? I hear they sound good, interested but don't have more than 500wRMS amp, and don't want to upgrade.... //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
