I bought the SSV Works iPod overhead stereo system for my 2011 RZR4. When I was installing it I found the wiring harness was to short. After mounting the front and rear speakers the plug to connect them was about 6" too short. I had to cut the plug off and extend the harness to be able to plug them together. I installed it to exact specs. The power wires that you run down to the battery were too short also. Had to extend them also. I am very disappointed in the lack of installation material and ease of install. The system works great and is built excellent. Just thought I would let everyone know in case your interested in purchasing!
