Okay so I just got this Fusion pp-am300010 and took out my Soundstream Picasso PCX1000d and the capacitor I had. Before installing the Fusion, it would hit hard and stay like it. Ever since changing to the Fusion, At low volume levels (under 25), the beat hits good and constant. Once I get past about 26 and up, the beat will hit hard for about 5 seconds then go "flat" as in not hit hard anymore". What could be causing this? Is it extreme voltage drop? Clipping? Should I put the capacitor back in? I currently have 4gauge and am going to do the big 3 tomorrow or this weekend in 0/1 and I have a stock battery.
