well first things first, i'm not sure if you were clipping or not, so if you haven't set your amps gains properly then definitely do that. if you have no clue what i'm talking about i'd be happy to explain lol.
I don't know if I was clipping or not either, cause I don't know what that sounds like. I just know that all the sudden, they sounded GOD awful. I'd like to think that the gain on the amp was correct as the store I got them from set it all up for me. I've gone thru 3 amps with them until I went with this one. I started with a PPI D1000 (I already owned it) and decided I wanted more so I went to a Kenwood (model # forgotten) but I was not happy with the Kenwood and then moved on to this Alpine amp.
I feel your pain. I go to school, work, have kids, and a marriage in Florida that I am working on, all while living in Virginia LOL
