Ok First thing... buy yourself a wireharness... trust me.. its better to spend 10 dollars then to have to cut your stock wiring...
with that said. i purchased my harness at local audio store so im sure you might be able to do the same.
if not look online
after that there is 1 wire you will have to cut, because on the back of our radio we have two harness's
we have 1 small plug and 1 large plug. you need the harness for the large plug because that is where all your audio wires are..
however, the small plug has your AMP_REMOTE (light blue) wire on it.
i connected this to the ignition wire off the large plug, so now whenever my car turns on AMP turns on...
i also have my PC connected to this with a switch in the middle.
but once you get the harness, it should tell you what wires are what speaker, hook up to RCA then get a Y adaptor to 1/8 plugs and plug into PC.
if you need more help from there PM me ill gladly help with what i can!
thanks!
