I have this amp, and it came under rated like all other MTX amps. I actually had 320 Watts @ 4ohms instead of 280Watts... Obviously this varies from amp to amp, but expect it to be under rated. MTX wont sell an amp if it doesnt meet or beat factory specs. Im now using the amp to power my internal speakers and it sounds great. So this amp is good for Internals or subs. Your Choice
*EDIT*
P.S. If u want me to take a pic of my amp so u know what it looks like let me know...
