Who did you buy it from? They could have had a 2500.1 and sold you the 600.1 with the birthsheet of the 2500. Compare the dimensions of your amp with the specs on kickers website.

its the kx 2500.1 HUGE!!! 30" long but want to know how much rms it really pushes beacuse in the future i want to run a btl 18" for now i have " i know some of you guys are gonna scream and say waist of money on subs but there 2 L5 15they came with the amp" but there only temporary till i buy a alternator 200+

Those subs will work fine. I would go with a BTL though. The reason they include the birthsheet is to show how many watts THAT amp pushes, so it probably does 2800 watts. My Rockford P400.4 is underrated 30 watts per channel.

I would go with 2500w rms instead as power at birtsheet are rated at 14.4v.
