Step 1: What You Will Need...
2X 12v LEDs (or more if you like(any color))(if you like you music really loud you will need to put in some resistors or higher voltage led's)
2X led holders (only needed if you are mounting them to the speaker housing(requires drilling if you go this way))
1X spool of wire (any color(its not complicated so you only need one))
I recommend heat shrinking the connections
oh ya and a set of speakers
tools you will need...
soldering gun and solder
drill and bit (if your mounting them in the speaker housing)
screw driver (to take your speakers apart)
Step 2: Open Up Your Speak's
most portable and PC speakers have screws in the back to hold the two plastic peaces together... remove these screws. some times they will have screws hiding under the stickers and battery cover... also they may have glued the edges together (thats what happened with my portable set)
Step 3: Mounting and Solder Your Leds In
1.B-if your not mounting them inside the housing(plastic out side) you can run the wire to the top of your speaker and glue the led to the top...
2.take your 12v LEDs and solder wire extensions to them, the length of the wire will depend on were you are putting you LEDs...
you should heat shrink the connections from led to wire, remember one heat shrink tube per wire connection, if you don't you WILL short out your speakers... use your soldering iron to shrink the tubing but don't touch it with the iron.
3. solder your newly extended wires and LEDs right to the largest speaker's terminals(dose not matter on polarity)
be sure to check the schematic below (it aint hard to read)
Step 4: Reassemble
Step 5: TIME TO TEST THEM OUT!!!
remember if you like you music really loud you will need to put in some resistors or higher voltage LED's, so if your lights look like there going full power then turn it down before you burn out you LED's
