I have A new pioneer headunit and i went to bestbuy yesterday to get the wire harness that connects to the factory wires and the person working told me that since I have the factory infinity system with factory amps then I might need two wiring harnesses or one depending on if the factory radio is Eclipse or Dodge can somone help me out i just want a system in my car and does the factory amps interfare with anything THANKS FOR LOOKING!!!!

 

I am guessing you have a coupe since you mentioned Eclipse. It doesn't matter either way, the radio is a Dodge head unit in both the sedan and Coupe. It is the same wiring harness that Dodge has used for years which is made up of 2 plugs. The kit you buyshould have both plugs, if not, go someplace else. Now make sure you do get the wiring harness for the Dodge Infinity system to correctly hook into your factory amp. This kit will have a set of RCA plugs for your speaker wires. You of course will need to plug these into the RCA outputs in the back of your Pioneer HU. You can use the regular kit but this one will not having the RCAs. Some people run them that way and say they have no problem, I have heard other that do have problems.
