No. A car radio uses so little power that it is completely impossible for it to even run down your battery a little bit. Using the air-con however, will wear out the battery and increase your fuel consumption.
I beg to differ with the above answer. Of course a radio will run down your battery if it is left on. Now if you are referring to the clock on the radio, then that uses very little power and it will take a long time for it to run the battery down. If your battery is running down overnight and the radio is not on playing music, look for some light somewhere that is on. Trunk, under-hood, curtorsey, glove box, dome, etc. It can also be a relay that is stuck. Lastly the battery itself can have a dead cell which will run the battery down overnight. To find out disconnect the negative battery cable overnight. If the battery is dead in the morning, replace it as it has a dead cell.
You may have to disconnect and recharge your car battery for your car stereo to work again.
connect the positive and negative to the stereo
yes, it is possible
Yes it can.
While the car is running the alternator should be recharging the battery faster than stereo can drain it. I suspect you either have a problem with the alternator or its time to get your battery replaced. Until you get it fixed, if you don't turn on the radio, it wont drain your battery :) If it is a high power model, it needs to be wired directly to the battery.
no you cannot kill your alternator by switching your battery from one car to another
Yes, the cassette is inserted into your car stereo which uses power from the battery.
The car will then be unable to start.
the stereo code is for when car battery is disconnected from car and radio locks up the code has to be put in again the number is located behind glovebox in 1995 model
Yes, IF the operating voltage of the stereo is the same as the battery output voltage of the vehicle.
When a stereo system drains too much battery power, it is time to add a capacitor. The capacitor will not increase the battery, but instead will modulate it allowing for additional stereo usage.
You need to re-enter the code for your stereo which can be found in the manual that should have been supplied with your car
