I have a JVC KD-R210 does it have a wire fore it or what do I do
it's the blue wire with the white strip on your head unit
The red wire off of the wiring harness for the radio is the remote wire. You need to run atleast a 16g wire(a 12 gauge wire would be best) from that red wire on the radio to the remote power input on the amp. I do not know what kind of setup and amp you have so I can not give further info, sorry.
