Its a KAC-9105D

My buddy said to do the big. 3 Upgrade

 

With the amount of current draw that the amp is able to produce you don't need a cap for starters. Yes the "Big 3" is always an upgrade to any system with beneficial results.
You had mentioned the "amp is all the way up" do you mean the gain is at the max? if so that is a definite problem, are you running an aftermarket headunit if so what is it?
Was your system professionally installed? What guage of power and ground wire is being used? Where is the ground cable grounded to and how long is it?
