These 12 volt stereo coolers are pretty cool and easy to make. I run this on a 12 volt system using an amp to power to speakers. I added a switch on the outside of the cooler also. These are great for camping, tailgating and in the back yard. I have an audio cable coming from the amp with the white and red connectors going to and 3.5mm male audio jack that plugs into a phone or ipod.

I recommend boat speakers

Step 1: Tools and Supplies


wire strippers

solder iron


electrical tape

jig saw

sharpee marker





heat shrink


aux cable

Step 2: Building

Once you have all the supplies for the stereo cooler you'll want to use a sharpee to mark the holes to be cut for the speakers, the switch and the audio jack. I traced the speakers and then used a jig saw to cut out the circles for the speakers. I then screwed them down into the cooler. I also then cut out a hole for switch between the speakers. Then i cut out a hole so the audio cable can come threw and don't have to have to shut the lid on the cable.

Step 3: Wiring

The wiring of the 12 volt stereo cooler is fairly straight forward. First I mounted the amp to the side of the cooler. There are 7 wires to be connected, and the red and white audio output plugs that convert into an audio jack. Of the 7 wires that I screwed into the amp four of them were for the speakers, 2 postive 2 negitive. Then there was a ground wire that I wired a connector to to plug into the battery. Then I have red wire coming out of the positve slot and a purple wire coming out of the remote slot. I soldered theses to together and then to the swtich. From the the switch I have a red wire with a connector going to the battery.

For transporting I put my 12 volt DC cooler inside with the battery packs in there.
