Step 1: Parts List
1 x old powered 5.1 PC speaker system.
1 x pair left over 100watt Pioneer car speakers (Paid $89.95 in 2000 for these)
1 x old suit case I got for $1 at a local pawn shop big enough for all of the stuff inside
1 x 12v 2 amp wall plug this was left over from the speaker system
1 x 12v 7amp battery from an old remote control toy
1 x audio aux cable $9 from radio shack
1 x female case mount power socket
1 x 2 way switch to switch power source between battery and wall wart
various bits of wire, connectors, tape, etc...
Drill with various bits
hot melt glue gun
For the labels:
I used Inkscape to create the labels out of some left over vinyl sheet. I cut these out using my wife's Cricut scrapbook cutter.
Step 2: Tear Down
Step 3: Mounting the Speakers
I put in the amp part and battery to see where the speakers would be mounted.
I marked the case where the grills would be with a sharpie and cut out the speaker holes with the hobby knife.
I mounted the speakers with various bolts I had around the shed.
The speaker grills were modified and will be hot glued on after everything is tested out.
Step 4: Wire It Up
I drilled a hold for the on/off switch, wall power plug, and audio input cable.
The power switch was hooked up to allow battery power when it is switched one way and wall power when it is switched the other way. the switch is off in the center position.
I wired up the wall power plug to the on/off switch.
I wired up the battery to the other side of the on/off switch, and I made a plug to go into the pc speaker amp and plugged it in.
I used hot glue to glue the power wires around the case so they would be out of the way.
Step 5: Finishing It Up
I printed out labels for the power switch, audio input, and wall input as well as a large logo for the front.
Things I still need to do:
Add in an LED to show when it is powered on.
Things I want to do:
I want to add a micro-controller controlling LEDs on the front doing some crazy disco patterns.
