What do i label the files as? 1.mp3 ? 001.mp3 ? do i just load up a tf card and put it in the slot ?

Does not matter how you label files. My plates is playing files in order they were stored to flush drive

Is this capable of loading and playing wav files?

Yes. I have used both .WAV and .MP3 files successfully

there is absolutely no base on mine. is there any way to increase the base or should i just return it?

You could 3D print a base. But if it's bass you seek then you need 10X the watts and a low-pass filter.

Where can I get the circuit diagram for this card? Looking to connect to arduino.

All I was able to find is what's on the web page where you bought it.
