OK so I basically stole this idea after seeing it at a friends party. However, I think that I improved on it some. Basically it is a regular cooler with a car battery and car stereo / car radio built in. This write up should serve as a decent How-To build a stereo cooler (aka cooler stereo, party cooler, beach stereo, etc).
It is perfect for car camping trips, tailgating, the beach, and basically anything not near a power source (including if the power goes out). I got an 88L igloo cooler for mine but any will do.
I chose to purchase most of my components online, starting with some 5.25 Boss marine speakers. I thought that mounting to the cooler was going to be difficult but after bending the supplied clips and inserting them behind the first layer of plastic it turned out extremely solid and easy.
The clip acts as a nut and washer behind the plastic.
Then I was able to mount the head unit and battery. I also threw in a 400w power inverter (far right) for small jobs and I’ll probably add a larger one later for larger tv’s etc. Above the inverter is a small battery charger and maintainer to keep the 115AH deep cycle marine battery topped off when at home. A simple switch panel at the bottom controls the charger, stereo and other components to the system.
Still to come is the marine subwoofer and amp, some 12v cigarette sockets and a solution to control the stereo via remote when the lid is closed. Just in case you were wondering why not mount the head unit through the cooler, I will be mainly using this car camping and It needs to be able to survive a heavy rain with no problems.
———————————–Update March 2010———————————–
This is the setup that I used for ~8 months. I have yet to find a good price on a 200-400 watt amplifier so I just wired the subwoofer as a rear speaker for now.
From West Marine I purchased a waterproof splash cover for the head unit. That allowed me to mount the stereo on the back side of the cooler for easy access. I lengthened the wires so that I can keep the sensor in the front.
The view from the front did not change. There is enough room on the front to move the current speakers to the sides and replace them with larger ones.
The cover is translucent and allows you to view the display easily while keeping any sand/moisture/water off.
Cover up.
The disconnect for the IR sensor that I moved to the front. This way the faceplate can be removed if needed without cutting any wires.
Whats next?
- Tidy up the wiring and mount everything securely
- Fuse block and kill switch
- Switches, volt meter, 12v cigarette plugs
- Cover for inside with switch and volt meter mounted in it
- Storage for cables
-Padded cushion top
- Wheel(s) for transportation.

Just wondering….how do you ground the stereo? Do you have to connect the negative post of the battery to anything? Can you connect the negative wire from the stereo to the negative terminal on the battery? Thanks in advance.

Yep, directly to the battery. I went to Academy Sports and got two “Bus Bars” one for the positive and one for negative. Basically it is a strip of metal with screws in it.

I was just curious how long you are able to run this system off of the battery alone, and how loud does it get?

With just the stereo going, you could run it loud for about a week (~168hrs) and it gets VERY loud. You could of course get higher wattage speakers and add an amp for the left right audio channels. The sound from this setup carries very far and is great for large outdoor parties / on a boat.. etc.

About to build the same thing.
I’m using a MB Quart 2×60 (RMS) Amp and Two Kicker box speakers with 6.5 woofers and 2×5 horns that will handle 75 watts RMS (fyi).
I’m powering it with a deep cycle group 24 battery. Any idea on how long this setup will last?
Also, I’ve never had a deep cycle battery before….do you get an automatic charger and hook it up after every use?

What about cooling? Seems like the heat generated from the components would be trapped inside….

@Susan, cooling is not a problem, all of these components are designed to take any ammount of heat, think about how hot your car can get in the summer.

Does the receiver have any trouble playing mounted vertical? I have noticed that several stereos I have been looking at for my cooler say they can play “up to 30 degrees above horizontal”. I don’t see what else it could mess up but the c.d. player though.

@ Nick, I was not using the cd player but have now turned it horizontal and mounted it to the outside so that the cd player is functional.
