DELL A425 SUBWOFFER PINOUT

Coda has flat D 6 pin with center pin grd for 4 wire vs old arrow 6 pin round black one. Flat on bottom, count cw 12345 pins w pin 6 center... 2 pin minus 12 v, 4 pin +12v. For other 4 wire like speed/temp... 1 blue, 3(top) white, 5 pin bot right yellow, 6 center ground for spd/temp. White for speed wheel, rest not known. I used 2wire cable and 4wire cable with 2ft pigtails and 3amp fuse in red wire. I used old radio stereo 2 and 4 pin male female connectors at end of pigtails.

Hi, I hope this helps,

Pins look like this: (Top view, not copper side)
1 2 3 4 5
6 7 8 9

1 = Thin white wire from thick white cable (Left input)
2 = Gray (Speaker out)
3 = Orange (+V return from volume unit to bass unit)
4 = Not connected
5 = Thin Red wire from thick red wire (Right input)
6 = Blue (+V power from bass unit to volume unit)
7 = Black (GND - if socket removed, solder 3 socket shield holes to each other or solder black wire directly leftmost hole)
8 = Not connected
9 = Shield copper from thick red wire

Shield copper from thick wire : Solder to GND or Left unconnected
