I have a 3rd Gen Prelude and the battery keeps dying when the car is parked. I installed a brand new battery and the car was parked for a couple of days, when I tried to start it everything's dead.
What could cause this? I think the previous owner installed an alarm because I see a box zip tied under the steerring column, I didn't get a remote for it though.
It could be a stereo that's wired wrong (stays on all the time) or it could be an amp that was installed wrong. That's pretty common, people tapping the remote wire to the wrong thing, so the amp stays on with the car off... kills the battery pretty quick.

With the car off and key out, hook up an amp-meter between your ground cable and negative battery terminal. Observe the amp-draw on the system. Start pulling fuses ONE AT A TIME, watching the amp-meter. When it goes down significantly, you've found a draw. Note: some devices will draw a very little amount all of the time, like your clock (as it always needs to keep time).
