03Honda Accord-How Do I wire another head unit plus keep dual climate stock head unit
I have a 03 honda accord coupe with dual climate control which means my air conidtion settings is displayed through my head unit.I purchased a stereo install kit to install a headunit below the existing one where the current hideaway compartment is. My question is how do I wire both of them so that they both function yet they dont interfer with one another while still keeping my air conditioning functions working. Should I wire the aftermarket bottom head unit power source to my 12 volt ciggerete liter or splice the wires to the existing power wires and speaker wires. I heard if you splice them together neither will work Any suggestions please. Im installing this extra head unit because I have a amp and subed hooked up and want to run to an aftermarket headunit which has more eq options thus provides better sound and bumb. Could just get an RCA or whatever you call it hook up to the stock head unit but doesnt allow me to eq the sound right. Here is a link to what my setup looks like with the 2 head units just concerd about wiring. THX ANY SUGGESTIONS WOULD BE APPRECIATED.
