Speakers and Their Circuits

Not that long ago I came up with a fun project idea when I was bored. I had some spare speakers laying around and felt like a fun thing to do would to add them to my current speaker system to help fill the room with sound better. To do this I drilled small holes in the back of my current computer speakers and then connected some wire in parallel, I then ran this wire through the ceiling and then soldered the leads to the speakers. By connecting them in parallel I reduced the resistance of the circuit but I also increased the current, thanks Ohms law! I thought this was all good, but then my dad brought up a good point, would the increase in current cause the amp in the speakers to blow. To my luck it seems like it all worked out fine as a few weeks later the speakers are working just as they were before. Another bit of physics that helped me in this project is magnetism. At the back of all speakers there is a sizable magnet used to vibrate the membrane and create the frequency of the music.  I used this magnet as a form of mounting, I have ceiling tiles in this room so I just stuck the speakers to the ceiling where the metal was in the ceiling and I was done!

Its always awesome when you can apply stuff we learn in physics to a practical use. I remember doing that lab last year.
