Are any other electronics in the vehicle acting up with this issue here at all?

O.k.,your radio factory or after market like it is here is powered by one feed wire from the fused battery output to keep the memory alive and one ignition switched on output from a fuse ignition switch signal.Since you have no other electrical faults in your vehicle here I dont suspect the ignition switch is the cause here.I suspect either the radio itself has shorted internally keeping it on needing removed and repaired or removed and replaced or the wiring has shorted at the back of the radio causing this here.

The only way to be sure is to remove the radio and locate the light green wire with yellow stripe,this should have power at all times with key on or off.It may be a light gray with yellow stripe.

The other wire is a yellow wire with black stripe.This should only have power with the key on or in accessory.If both of these wires test good and no shorts are found in the wiring then the radio is at fault internally needing repaired or replaced.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete
