Hi stowya3,

They may use ISO pattern connectors, but they're not ISO! There is an amp in the sub for the rear speakers and this requires power from the head unit. If you just plug your new unit into the existing harness you'll only get sound from the front speakers.

You need a harness adaptor to make the rear set work properly, I got an Autoleads 06-104B harness adaptor and everything works a treat.

Hope that helps

Jon
