Seriously, nice system, just don't get carried away with all that power.
In a real world scenario, this system is only twice as loud as a 300 watt (RMS) system from yesteryear, but it will be cleaner, and have ability to process peaks of almost twice that range. Having lots of headroom is almost always a blessing. A strong vocalist can suck up the entire available power with one note. Good luck with your new rig!
