Recently Changed Amps From A 800 Watt To A 1800 Watt. Everything Was Right And Sounded Good And Loud Before. Now With This 1800 Watt, After About Ten Mins Of Playing, My Highs Which Arent Amped Get Quite And Kinda Sounds Muffled...... Why Is This And What Can I Do To Fix It ??? ( Never Had This Problem Ever With Any Of My Systems )
