Audio Stuff: Alpine KTP-445U and LC7i

I’m new to audio stuff so I’m confused with things. I just installed Rockford Fosgate Prime speakers in my truck and they feel under powered. Does anyone know how to wire the Alpine amp and the LC7i? Do I need the LC7i? I read somewhere that the tacoma’s don’t have bass roll off. Also I want to get the seicane aftermarket head unit. Does anyone make a plug and play harness for all of these things?
