Well here is my dilemma...
I just upgraded my amp; from a 612 Watt Rockford Fosgateto a new Power Acoustik Area 51 520x2 amp in to go with my Pioneer Premier 800W 12's. The amp is actualy a friend of mine's and hes letting me borrow it for a while. When we put it in he bridged it. My system was hitting really hard for a while, and I played around with it a little. I don't now anything about audio stuff, and now they hit a lot softer, still harder than the old amp, but no where near where they used to be? Did I blow the amp, or the subs? Can anyone give me an idea as to what maybe have happened?
