battery drainage problem

[s14noob]

i need on some advice on where to start looking for this problem or it's just normal. if i don't drive my car or start the car for 24 hours, my battery dies. even with the alarm off. the battery is new, there's nothing wrong with the alternator so could someone tell me what to look for. this is what i have installed on my car. I have a compustar alarm with 3 led lights installed in the car when it's armed and i'm running two 10" type r's and a amp.

i installed a after market fog light switch and that thing drained my batteries one time when i left it just sitting at home for few month.

get a voltmeter that will check draw, hook it up in series with your contacts and see how much it draws with the car off. if it is more than .5 amps with everything off, chase the problem with the voltmeter. problem solved. i would get a new battery anyway if the car has died so many times. there is something called duty cycles on a battery. google it.
