Hey I just realized im an idiot. I figured out why I keep blowing my component set. I am getting my new cdt ef-61 component set today. These will be my front speakers. My rear are 6x9 infinity kappas. They run to a 4-channel jbl gto 75.4. I have a muti meter and the web site for the tones (http://www.realmofexcursion.com/downloads.html) but I dont get how to set the gains for the speakers. Any help would be greatly appreciated.
