I got one of those small portable DVD players. I got it mainly for when I go camping, or want to watch a movie when I work in the garage, or when I have to wait in the car for my wife, while she is shopping.
I wasn't looking for anything complicated or costly. I picked up a cheap model and it works pretty well for the price. The only problem is that the sound volume is too low. At full volume it can only be heard about 10 feet away at most, and if there's traffic outside I can barely hear it. The thought occurred to me to connect it to a car stereo, but then I got to carry all that stuff around plus a car battery.
Then it occurred to me to consider the amplified computer speakers that contain a couple D batteries. The DVD player has a earphone jack. Can these computer speakers be connected to this earphone jack? There is also 2 audio and one Video output jack (RCA jacks), but PC speakers have mini jacks in stereo. I actually intend to combine the
2 channels inside the speaker if this works. I dont need stereo or want to haul 2 speakers around.
