the first amp I fell in love with was the rockford P1000. I tell this story to everyone, but I had a hifonics brz1700 on 2 p3 15's and then I had a earthquake Ph-D10000 on the same setup, then I just randomly decided to put a P1000 on the setup temporarily and I was sooooo surprised. It s@*t on both the other amps and was rated 700 rms less than the hifonics and 2000 rms less than the earthquake! It was such a beast and I've been on rockford amps ever since. However, I did just get my first Sundown amp
