Is there anyway I can get my antenna to work? The headunit is a pioneer 6950HD or something like that, the antenna is plugged in but it won't work. I also didn't wire it, I bought one of those plugin adapters.

Cheers.

Does the adapter have the power aerial wire connected? If you are running a pioneer HU, it will need to be connected to your amp remote wire (as the pioneer units do not have a seperate out for the aerial). If you are running one of the aerpro adapeters it will be the solid blue wire connected to the blue/white that has the shielded female spade connector on the HU (assuming that you had to join the 2 halves of the loom together).
