After figuring out all the wiring issues for the ServoNaut sound system I went to work installing it. I decided to give it a "stereo system" style installation, instead of just hiding it in the trailer. While it's still going to be be hidden between the cab and trailer, but when the cab is leaned forward, it will look impressive.
So I took a hole-saw and cut a hole in the center of the front of the trailer. I also used the hole-saw you cut a piece of 1:16 diamond plate aluminum sheet. I mounted the speaker inside the trailer facing out the hole. Them placed aluminum screen over the hole and the diamond plate over that. I mounted the sounds system micro volume controller in between the air cleaners.
The trailer is almost full of electronics and wiring, so I guess I'm almost done!
