You are running the battery down.

How??

Keep the auto running if you wish to run the electrical components for more then 10 minutes.

I was asking you, if I keep using the radio for 45+mins will it drain my battery? Because that exactly what happen today, of ues, how can i get the car to start?

Yes, it will drain a battery and depends on how good the battery on how long it will go before draining to low to then crank the engine up.

You need to get a set of jumper cables and another car and jump it off.

Jump the car off with another car. Run the jumper cables positive to positive from one car battery terminals to the next car battery terminals and same for negative to negative battery terminals. May have to let the other car run for a few minutes with jumper cables hooked up so your battery can recharge then try to start it.

Could also use a booster box (has a battery & cables to hook to battery terminals). Remember red to positive and black to negative.

May can call a friend to come jump you off with their car. Or a tow truck road service, any one you know have jumper cables that can help you.

If you are not at home or stuck somewhere call a tow company, or anyone you know that may have jumper cables, or can give a ride to 24 hour store like a wally world of some gas stations to get a set of jumper cables then run the cables battery to battery from yours to theirs red to positive + battery terminals then the black to negative terminals - let it theirs run a few minutes before trying to start yours if it does not start then let theirs run longer do not keep trying to start it up for more than a few seconds as to keep from burning up the jumper cables so just let their car run a little longer before trying next time
