I sold the amps and subs out of my car for 3 car payments! But do i need to worry about the 3rd plug in if i don't have any amps or subs in the back? And yes the plug ins are just hanging out in the trunk not connected to anything
There are 3 plugs in the dash as you describe. The largest one has all the speakers and tweeters in it. The smaller one has amp controls in it and the medium one that has only a couple wires aren't used when installing a new H/U. If the system works without the amps and subs now, you shouldn't have any problems with the new system. It is a pretty easy install. I soldered and shrink wrapped all my connections with the 12v to 5v amp turn on converter in about an hour. That's amps, main harness, grounds, and converter. So you shouldn't need to worry about the amps wiring harness in the dash. I hope this answered your question. You should only need the main harness.
