Yes but since im not really powering my sub to its fullest im not getting all it can do, my thoughts are if i down grade a sub and be able to push it more would i end up with sououd improvements
You dont have to power it to its fullest. It will have other benefits over lesser subs than just greater power handling. It may have a flatter frequency response and sound better and may also be more efficient. So I'd stay with that sub and just tune your amp to be as clean as possible.
The greater power handling means that you can upgrade the amp in the future just to get it a bit louder. But you dont have to if it sounds the way you want.
Yeah but im not even powering it to its reccomended rms rating but if i do the big three on a 90 amp alternator i shouldnt have dimming lights at 1000 watts rms?
