Picture of River Radio- Floating Stereo that ROCKS!

A few years back a friend wanted me to build a floating stereo for his yearly lazy river trip. We didn't have the funds at the time but since I opened up a stereo installation shop I've gotten access to tons of cheap and second hand parts. This year I got invited to go on a lazy river down the Wisconsin river so I knew it was the right time to build a prototype.

The ice chest/cooler boom box has been done 1000 times so I knew I had to think of something different, and I didn't want to completely butcher a working cooler. My original sketches were to made a floating unit that looked like an ocean buoy but that had speakers built into it. My second sketch was to make a tall pyramid of the iconic yellow "Slippery When Wet" sign. However after some thought I decided that I should try to make this particular radio have as low a center of gravity as possible. Many other ideas including cup holders, waterproof storage etc were thrown out in lieu of cost effectiveness and time to build. Bottom line we've got a dedicated stereo with a simple design.

As per usual, I forgot to take as many pictures as I would have liked during the build process, please feel free to ask any questions.

How light was it and do u think a car battery would work instead of a landowner battery
hamsammy (author)  camguy1166 months ago
It ended up being not too light with everything in it. A car battery might last a little longer but the stereo battery I got lasted all day anyway, so why spend the extra and bear the extra weight? I used a kinetik HC600, not a lawn mower battery.

How do you access the battery to charge it?

The top comes off with 4 screws. I just hit them with my cordless drill and I have access to all the electronics.

No action shots?

Didn't build waterproof storage into this guy, so I didn't take my phone with on the river. I'll work on it though.

You should put a solar panel on top so you never worry about the battery going dead when out on the water!

That's a great idea! I didn't even think about doing that. I may underestimate the power generated by new solar panels and write it off.

This rocks. Great job on both your project and your instructable. I'm on the water a lot and I love what you've done here.

Haven't done any river tubing for a looooong time. This makes me want to get out on the water really bad. Nice work.
