Introduction: Carry Cooler Box Speaker
I integrated power amp and a speaker into small carry cooler box.
Step 1: Power Amp PCB
I maked power amp with LM386. I use one LM386 for one channel.
PCB is fixed with double-stick tape.
Step 2: Speaker
In this cooler box, the inside became dual structure. Therefore, I fixed the speaker in an internal housing.
I used a screw for fixation and blocked up the gap with silicon.
Step 3: Waterproofing and Wiring
I thought about waterproofing of a speaker and covered it with Tupper. And I filled up a gap with silicon in the same way.
A battery uses 006P.
A battery is fixed with a board of aluminum like a picture, because I do not enter a gap of a housing of dual structure.
Step 4: Suitable for One Person Hiking
Music and beer! It's the best combination.

I had the same idea but with no beer in mind, I'm using an ammunition can. I am though, having circuit problems. Below is the wiring diagram that I used. Tell me if i need to change anything because it buzzes and the amplified audio is choppy.

Good Job! Here is a suggestion. Try hooking up a solar cell and a rechargeable battery and keep the battery charged.

Thanks Murf. I was anything weak in English, and it was difficult to explain it. But did you understand it with a photograph?
