Step 3: Opening
- First of all i used a screw driver to unscrew the 4 screw on the SMPS
- And then i opened the SMPS
- and again i unscrew the main PCB board and removed it "See the image "
- and then i unscrew the power input socket
- and then i unscrew the fan
- and then i cleaned it with some old cloth
Step 4: Drilling
- I drilled 4 holes to mount the Main amplifier board " you have to figure that out "
- I drilled 1 small hole for speakon connector and i used a step drill bit to match the Speakon Dimension
- And then i drilled 2 small holes for RCA input and then i used a step drill bit to match the RCA Dimension
- And then i drilled a small hole for volume port and used a step drill bit to match the port dimension
- And then i took a Copper Clad to cover the power input hole and did some hole to match the port dimension "See the Image "
Step 5: Giving It Some Look
- I used Carbon Fiber Vinyl Red & Black to give it such look
- First i cover the Copper clad with red vinyl
- and Secondly i cover the SMPS Body
- Don't Forget to cut out the air vents
Step 6: Installation
- Firstly i stick the copper clad with some super glue
- and then i installed volume port to the copper clad
- and then i installed the fan
- and then i installed the Speakon Connector
- and then i installed the RCA input Socket
Step 7: Connections
- I Soldered some stereo wire to the RCA input
- and then i used a female header to soldered the end
- and then i used 2 wire to solder the speaker output on the Amplifier Board
- and then again i used 2 wire to Solder the Power Input on the Amplifier Board
- and then i used 4 screw to screw the main amplifier board to the SMPS box
- and then i used ribbon wire to connect the Amplifier board to volume control board
- and then i soldered the 2 speaker output wire coming from the amplifier board to Speakon Connector and used a heat-shrink tube to secure the connection
- and then i connected XT60 connector to the power input wire coming from the amplifier
- and i used some hot glue to stick the XT60 to the box " See the Image "
- and then i connected female header coming from RCA input wire to the Volume control board
Step 8: Fan Controller
- I used a temperature controlled switch for turning on the fan at 50 degree Celsius
- I soldered 2 wire on the amplifier board " the amplifier converts 48v to 12v dc for the fan "
- and then i connected 2 wire to the control board
- and then i connected fan wire to the control board
- and then i used dual sided tape to hold the board to the SMPS box " See the Image"
- and then i connected temperature sensor to the control board
- and then i powered the whole thing up with a 48V 10A power supply
- and then i set the trigger temperature
- and then i used some silicone glue to stick the sensor to heat-sink
- and then i used 2 led and a resistance in series and connected to the 12v rail
Set the Temperature
- tap to set button
- tap to "+" and "-" to set the temperature
- tap set button to save the settings
Step 9: Finishing
Close the SMPS box and screw the 4 screw
