I have my Kenwood 2513ps running @ 450 rms from my Brutus, and it really isnt that much while driving. I just installed new 4 gauge wiring, and im installing my new Zeus amp today to get the most out of my speakers. I have my Amp tuned to about 110hz, as i am trying to hit the bass guitar in the the songs i listen to, as my speakers are pretty small. So, since i love SQ and hate that droning bass from ported boxes, will a 2012 Type R running 900rms be enough for me? Or does the Type R have to be ported to really shine? Im fairly new to everything, although i have installed everything cleanly myself.
