Does anyone have a starting point for doing this system like will I have to remove the radio? Is there a wiring diagram specifically for the audio wiring? I have two Kenwood Excelon 10" subs(200watts RMS and 800 watts), KAC-X522 2 channel (RMS Power Range : 165-254 Watts, Max 1000 watts), 2 KFC-XR60P component sets (both 88 watts RMS and Peak 180 Watts), KAC-x542 4 channel amp (88-124 Watts each channel, Max 960 watts). Everything will be wired at 4 OHMS. I wasn't planning on changing the center channel and the tweeters in the dash but is it recommended and if so is the four channel amp going to be enought to push some small but better than the factory speakers? I know this isn't a system to stop traffic but I'm sure it will have that knock I've been missing with the garbage factory system. I just want to get this in as easy as possible and opinions on what I'm using be appreciated. I haven't seen anyone ever speak about keeping the whole system one manufacturer and Kenwood excelon of all things. Thanks in advance!!!!
