| watching movies, how is it on car batteries?
I'm just wondering how bad is it to watch a full 2 hour movie on your car battery? The engine isn't on just the power for the dvd din.
I have a 7" screen, it reads video's from a memory card. I'm not running any dvd's.
car: 5th gen prelude.
Any info would be great, thanks!

With no subs, no external amplifier I think you could pull 2 hours out of it at low volumes with a good battery. Cut that time in half with an ass battery at moderate volumes. There are so many variables to give you a real accurate answer. I wouldn't risk it though and run your battery dead. A voltmeter is also a good tool to at least monitor your power.

In my other car, I couldn't justify spending 100+ bucks on a voltmeter, so I did some research and found one on eBay for dirt cheap. It's from HK and the thing works like a charm.
I worried at first about the quality, but it's awesome. http://cgi.ebay.ca/Blue-LCD-Volt-Met...#ht_2764wt_977
Check out some of the other styles in his eBay Store.
Nothing beats a Dakota Digital, but if you ain't got the money, this is the next best thing.
The item has two leads. Positive and negative. You connect them in line with your stereo power lines. That's it. Accuracy is pretty good.

More volume = more power used. Some amps are efficient, while others aren't. Bass takes a lot of power. Deck alone does not take too much power to run - the internal amp does.
I would say one movie at normal to low volume is about all you can run on a battery in good condition. Then again, a Honda Civic or Fit uses such a puny battery even that might not be enough to power any device for more than 15 minutes without the engine running.
This is why a voltmeter is so important. The beauty of the Dakota Digital voltmenter I mentioned in the previous post is it has a user settable low voltage warning point. I set mine at 10 volts. Any time the voltage drops to 10 volts, the display does the funky chicken and flashes. It has saved me a few times. Before I start the truck up, I disconnect the sensor wire to the solenoid and it prevents the drained aux battery from draining the main battery upon crank.
If you are like me and watch a lot of movies while others go shopping (like the wife and daughter), a second battery is a must. I have an Optima Yellow in my truck and a Kinetik HC800 in my other car. The Kinetik is awesome. Got mine from Orgasm Donor for a damn good price. So small, yet so powerful.
Edit: my other car, BTW, is a Honda Fit, and the battery it came with is just powerful enough for a granny in a powered wheelchair to drive three blocks and back. No kidding, it sucks ass. I mention the powered wheel chair because the battery is about the size of one of those found in a powered wheel chair. If I listened to a Canuck game on the radio with the motor not running in my Fit, the stock battery might last me enough to hear the other team score a goal on Luongo. That's like what? 6 minutes? LOL

get an Optima batter with higher reserve capacity to maximize your dvd time =)
or do a dual battery setup with a battery isolator
