Most stereo head units have two 12v positive lines coming into them - one is actual power from the main solenoid/battery, and the second is a "power on signal line" from an ignition circuit that tells the unit to turn on and draw its power from that first power line. Check your unit to see if those two have been spliced together, and if so, separate them back out and make sure the signal line is tied to an ignition-on circuit.
Alternatively, just wire a switch between the unit's main power source and the unit and flip it on and off as needed.
