Until the Kicker amp gets here, I was going to use the good ole Punch 500a2 and give it 250wrms at 2 ohms. Do you think that underpowering it that much will do some damage to the sub? The box design I used (from Kicker) called for 500wrms with subsonic filter, 350wrms without. I don't have a subsonic filter for the 500a2, so I didn't think 250wrms would be too bad
