not getting louder, I even tried switching all the speaker wires in case they were reversed or something...no go...im using a $20 monster cable from my board...this sure is frustrating...i plugged my ipod in and the sound was great, but I dont know about 500watts, it only sounds as loud as my 150w stereo and thats on 11 overdrive...the keyboard is even worse, its just about as loud as my 30watt guitar amp, just way nicer sounding...i hope this one gets solved...
thanks
