Yo, I just purchased an amp called "Performance Teknique 773" for my MB QUARTS QSD 216 and my back speakers infinity kappas. You think this will do the job? Or should I upgrade? Dealer told me that amp doesn't really matter (only watt wise) when it comes to component speakers. But I think he is full of sh*t but I just bought it anyways cuz I was on a budget. So what do you guys think? Does AMP really matter (besides wattage)? Do you think the amp "Performance Teknique 773" will go great with the MB QUARTS QSD 216?
