Also, i had to look it up...that small of an amp didn't really look like it could put out 2000W RMS....not to say one cant, i just couldn't justify it...
turns out a hunch was right.

It's mu-dimension even though it says "u" dimension.
His subs should be fine at 500W RMS a piece since he's got the 1000WRMS version of the amp.
