this amp is the worst on the market

i just got this amp hoping it would sound at least better than my rockford punch 500 watt amp, let me tell you, my subs are HARDLY moving, this thing may be 200 watts, my 500 watt amp pushed my subs 5 times hardly literally, DO not buy this piece of crap, i could hardly even tell it was on. I have been installing car stereos and systems for 7 years on the side. i know what im doing this is just a horrible amp
