I only need them for music. And its just the right and left speaker. But my question is. Is it ok to use these speakers the way I am using them. I plan to get a rockville amp with Bluetooth so i can use my phone instead of a USB stick. Also I am pretty sure that this technical pro amp is not 600 watts like it says. It seems week
