Running a 10" JL (300 RMS) on an Alpine amp at 150 RMS at 4 ohms and I just fried it. Same happened to my last 10" Punch. I thought i had the sub matched perfectly to my amp but obviously I am doing something wrong. Anyone know of any good instructional material I can read to educate myself before I waste any more money? I wanted to upgrade my sub and amp but not if I am going to just ruin another driver. I do listen with the bass boost up and at high volume, I am definitely hard on my subs, but thats why I was careful not to over power this one. What else could I be doing wrong? HELP!
