Home used subwoofer can connect to car?

I have a home used subwoofer with 220V AC. It has a transformer input of 220V AC, and Output of 12V 2A. I want to fix that subwoofer unit into my boot of the car. My car is running on 12V NS 60 Car battery. To run the unit with car battery I may have to bypass the transformer of the unit and give power from the battery directly to the Amplifier. I have two questions. 1. Is it safe to get a direct power line from the car battery to the unit. 2. How to identify the place in the circuit board to connect the power line from the car battery. (Sample diagrams are very much appreciated)

you should be able to wire it directly off the battery. Put a fuse inline Bigger than 2 amp in case it tries to draw more current than the wires can handle.

well i dont know about car battries but once i pluged out transformer from my sound box and connected it with 9v battrie it worked pretty well with 0% damage

The 9V batteries I know of are not even able to supply 500ma let alone the 2 amperes
called out by the subwoofer power needs.

It can be done. you'll just need an inverter that can handle the power needs of the amp.
