In a way. When the engine is running the alternator supplies DC current to all electrical devices in the vehicle. When the key is in the "ACC" position, then the battery is powering the sound system. The radios don't take up much juice by CD or tape players will run the battery down to the point there's not enough power to turn over the starter.

Why Stock cdplayer in 94 accord will not work but radio will after battery went dead I put code in just the radio came on though how can I fix this?
Sometimes, a factory radio will work and not the CD player because the CD player is broken. Also, some makes of car radios only turn the CD portion of the sound system on when a CD Rom is physically pushed gently into the sleeve. Doing this causes the CD player portion of the sound system to activate it's power-on. Also, if you can use your radio when the car battery is nearly dead, just remember this: a car radio takes very, very low amounts of 12 volt battery power to operate. Imagine it's just a bit more than say...a 9 volt battery. Your battery may not have enough power/juice left in it to start your car with cold cranking amps/power but it does have enough left deep inside to operate your battery. Starting a car takes more power from the battery, a lot more. Starting a tiny radio takes very little.

By changing the battery, you erased your car's computer presets. Your car probably has an anti-theft radio, that locks when power is lost to it, and requires a factory security code to unlock it. The code might be in a section of the owner's manual, but if you cannot find it, you have to go to a new car dealership and have them reset the radio.
