Anyway, here's how I'd do it:
1. Get an ammeter that can measure at least 10A
2. Turn off the ignition and remove the key
3. Disconnect the NEGATIVE terminal on the battery and install the ammeter in between the battery (-) terminal and the other on the cable you removed. On digital ammeters, polarity isn't going to be a problem. But if you're using an analog ammeter, connect the (+) probe to the cable and the (-) probe to the battery (-) terminal
4. Measure the current.
4a. If it's <50mA, your car's likely normal. The battery may be losing its charge by itself
4b. If it's >50mA, proceed to #5
5. Try pulling out fuses one after another and see if you can find the culprit

You can be more methodical with the fuse pulling by beginning with the radio, alarm, amps, clock, etc... anything that is always powered up. And if you pull one fuse and see nothing happen on the ammeter readings, put it back in before pulling out the next one. BE SURE TO PUT FUSES BACK TO THEIR ORIGINAL PLACES.

Good luck!
wala akong amplifier or any audio setup. all stock lights and radio. anyway, try ko rin na isolate ang fuses. tnx.
