First a problem with the ignition relay in the underhood fuse box, label under the cover tells were it was at. First sign of dirty contacts was the radio in my Cruze.
Second problem that screwed up a lot more than the radio, was large voltage drop across the negative battery cable. Not the old one, but the new one with the correct clamp on it. Was inside the negative battery terminal where that large cable is crimped in. Was all corroded on the inside. Just took it is apart and soldered it.
Ignition relay sure has tiny contacts for up to a 45 amp load.

On practically all relays, a circuit is shown for the solenoid and contacts, also the solenoid voltage and contact rating is specified. On this relay, it ain't got anything.
