How is my system going to sound for the last time?

okay like i said i have a saturn and now i have a rockford fosgate prime 300 4 channel amplifier to power the alpine sps 600 speakers running on a second battery and i have the mtx thunder square 12s in a ported box powered by the alpine mrp m1000 so its going to sound pretty beastlt right? o and the fosgate amp i havent got it but its got a certificate system like kicker does that gives it more watts then it says so it will be closer to the 80 watts that the alpine speakers can handle.
