This is a pic of the sound board boxes and the wire loom coming from the bottom of them with the green circles around them and then going into the tubing.

The earphones I bought came with an adaptor the green circle.

I took that and cut off the male end and striped the wires cut and put on heat shrink tubing and wired that to the Dupont wires coming from the sound boars for the speakers. That way if I wanted to upgrade the earphones later I can use any style of earphones I want, they'll just plug right in.

Where did you find the upgrades the padding, the ear phones, and the voice changers?

The only drawback is that the sound wheel is connected in-between the earphones and the jack so if I want to change the earphones I'll need to rewire the sound wheel so It's on the other plug that is wired to the sound boards

The padding I found from a guy on the 501 junkyard but I found some from another web site that I have on order and just waiting on. If you your interested when I get the shipment I can sell you some. The earphones, Dupont wire, switches, and battery boxes I found on ebay

The sound boards I got from Amazon, there for the earphones inside the lid so you can hear the things going on outside. there not voice changers but if you want a trooper voice board send Jim from Hyperdyne labs an email, he's getting ready to do a run on some really sick voice boards. there a little expensive but well worth the price. They are very rare as he does very very limited runs on these get one while you can It might be another year or so before he might do another run.

Once I had all my wiring put together I wired in the battery boxes, the battery boxes are made pretty cheap so I took them apart and added hot glue to all the wiring. How did I know this? When I was putting in the box it slipped and dropped down and pulled the wires off the connections inside, you can't use a typical solder gun to reattach the wires it melts the plastic before getting hot enough to melt the solder, I don't have a cold solder gun and I don't know if that would work, what I do know is the hot glue sticks very well to these components so I use that to reattach the wires and It worked fantastic!!! very solid boxes now!!

I wanted to test my sound system before I put it inside the bucket in case I needed to do some trouble shooting.

Better to find out something isn't working before you take the time to install it then have to take it out to find the problem.

There are some things you have to remember about this system, it has multiple on/off switches, and multiple volume controls.

It has an on/off switch on each sound board marked with the orange square, and a volume wheel marked with the green circle
