Sounds like you have it wired wrong. No car stereo should draw that
much with power off. It should have a "Batt" or "+12 V" connection,
which goes to the always on source. It should also have an "Ignition"
lead, which goes to a source which is switched (usually the key, but
maybe a separate switch). As long as the  "Ignition" connection is off,
it should draw no more than about 10-20 mA.
