Hey does anyone with experience using PA systems? I found this on my local craigslist:

Phonic PA system includes 440W 7-channel powered mixer with DFX (reverb, tap delay, chorus, ect) and a set of matching speakers (15" woofer and a Piezo tweeter each). Purchased in December and barely used, still in like-new condition. I hate to part with it but I can't use it at my new place. This is great as a first PA system for a highschool band ect!

for 350...

Would this be enough for a metal band with drums? I sing clean as well so shouldnt sound distorted.
