first make sure ur antena is actually hooked up, like my car the antena is powered so it comes up, but it only works with the stock stereo cuse there's something in the system that tells it to come up. So with an aftermarket head unit the antena doesnt even come up anymore, radio still works but it kinda sux.
i have a kenwood KDC 1028, and there shouldnt be anything wrong with the radio, and the speakers are hooked up to the radio, so powering off of that, they didnt have a problem before, but now it does
