    Vey well done, awesome job. Is there any chance of seeing a diagram of how you wired it up, really like the design. I see the three pots for I guess the volume, bass and treble but the board specified does no have them from what I can see, was there another board? I have several old ammo cans needing this installed, again thanks for sharing!
