My radio does not draw much electricity, and my battery charger produces lots. So I could do this. Sounds like your sound system may draw more power, and I have no idea how many amps your charger puts out. Disconnect the battery, hook up the charger to the cables and see what happens

Car batteries are not designed, engineered nor constructed for this activity. This can ruin the battery. Cars are for transportation not sound stages with audio systems. If you notice battery chargers are trickle battery chargers meaning they provide low voltage to a battery that is low on charge. This will not carry the load of the sound system in the car.

You should be O.K if the amperage your charger is putting out is greater than the amperage your sound system is pulling. When the car is running, your alternator is supplying the electricity and its connected to the battery. If you are not having problems pulling your battery down when the car is running, you shouldn't have problems when you are on the charger. Your charger is simply acting as your alternator. One way you can monitor the battery is with a voltmeter (or multimeter). a normal battery will read 12 volts. when the car is running it will read about 14 volts due to the alternator voltage. Periodically check the battery while you're running your system with the battery charger on. If the voltage stays at 12 you're not pulling the battery down. If the voltage starts falling, your system is pulling your battery down.
